Abstract:
Abstract: Arynes are a unique class of intermediates used in synthetic organic chemistry, and research interest has been intensely focused on their peculiar reactivities. Arynes have been researched for almost a century. However, difficulties in monitoring these reactive species, as well as difficulties in creating synthetically viable techniques for their synthesis and trapping, have restricted their application. A key tactic for achieving the racemic and enantiopure total synthesis of a broad variety of natural compounds or their structural derivatives. The chemistry of arynes has advanced significantly over the past thirty years, particularly in the field of transition metal carbon- carbon and carbon-heteroatom bond-forming mechanisms. The field’s fast growth is largely attributable to the development of mild aryne production processes. To create a natural product with complex organic molecules, the role of aryne intermediates was non-replaceable. These organic substances are often used in medicine, therapies, or as raw material for the synthesis of other substances. Moreover, they may perform important biological tasks. There are numerous methods for synthesizing natural compounds including total synthesis, semi-synthesis, and biosynthesis. Total synthesis is the process of creating natural products entirely chemically from basic precursors as well as it can be produced in large quantities and can reveal information about its biological activity. One of the developments in Arynes’ chemistry is the chemical rearrangements brought about by this electrophilic intermediate. It is not feasible to use conventional methods in a single step. This review article discusses how arynes are used to create natural products. Arynes has a wide range of functionality in the field of scientific research. The evolution of this method has made a tremendous change in the total synthesis of natural products. Benzynes enabled creative synthesis in mild conditions. The transformation has expanded to investigate various reaction classes such as nucleophilic addition, (4+2), and (2+2) cycloaddition strategies and metal-catalyzed reactions are shown and explained in this article. This review will provide an idea about how the arynes act as an intermediate in those reaction mechanisms and enlighten the scope of these aryne intermediate.

Abstract:
Natural products, with their array of structural complexity, diversity, and biological activity, have inspired generations of chemists and driven the advancement of techniques in their total syntheses. The field of natural product synthesis continuously evolves through the development of methodologies to improve stereoselectivity, yield, scalability, substrate scope, late-stage functionalization, and/or enable novel reactions. One of the more interesting and unique techniques to emerge in the last thirty years is the use of chemoenzymatic reactions in the synthesis of natural products. This review highlights some of the recent examples and progress in the chemoenzymatic synthesis of natural products from 2019–2022.

Abstract:
Natural products play a key role in innovative drug discovery. To explore the potential application of natural products and their analogues in pharmacology, total synthesis is a key tool that provides natural product candidates and synthetic analogues for drug development and potential clinical trials. Deconstructive synthesis, namely building new, challenging structures through bond cleavage of easily accessible moieties, has emerged as a useful design principle in synthesizing bioactive natural products. Divergent synthesis, namely synthesizing many natural products from a common intermediate, can improve the efficiency of chemical synthesis and generate libraries of molecules with unprecedented structural diversity. In this review, we will firstly introduce five recent and excellent examples of deconstructive and divergent syntheses of natural products (2021–2023). Then, we will summarize our previous work on the deconstructive and divergent synthesis of natural products to demonstrate the high efficiency and simplicity of these two strategies in the field of total synthesis.

Abstract:
1,2-Dithiolan-3-one-1-oxide exists in antihumor antibiotic leinamycin and can cause DNA cleavage in the presence of thiols. Diastereoselective synthesis of this unique ring system has been achieved by low temperature oxidation of the corresponding 1,2-dithiolan-3-ones with 3,3-dimethyldioxirane. 5-Methyl-1,2-dithiolan-3-one-1-oxides were synthesized by oxidation of 5-methyl-1,2-dithiolan-3-one with 3,3-dimethyldioxirane. Eu(fod)₃ and C₆D₆ induced proton chemical shift studies showed that the major isomer in the product has a trans sulfoxide relative to the 5-methyl group. Low temperature oxidation of 4-substituted-amino-5,5-dimethyl-1,2-dithiolan-3-ones by 3,3-dimethyldioxirane preferentially led to the corresponding trans-1,2-dithiolan-3-one-1-oxides. This assignment was made on the basis of a X-ray crystallographic structure study. Formation of azlactones as well as 1,2-dithiolan-3-one-1,1-dioxide were also observed when some substituted 1,2-dithiolan-3-ones were oxidized by 3,3-ditnethyldioxirane. Three 2,2-dimethyl-1,3-dithian-4-ones were synthesized by SnCl₄ mediated condensation of β-mercaptothioacids and acetone. Oxidation of 2,2,6-trimethyl-1,3-dithian-4-one with Ce(IV) did not give 1,2-dithiolan-3-one or 1,2-dithiolan-3-one-1-oxides as anticipated; 1,3-dithian-5-en-4-one was detected as the product instead. Synthetic approaches toward loline were explored. Intramolecular photoaddition of bicyclic olefinic N-nitrosamine did not give the desired product. An epoxide approach did not furnish loline due to unsuccessful epoxide ring opening by azide ion. In the urea approach, the tertiary nitrogen of the bicyclic urea preferentially undergoes a transannular iodocyclization. The same results were obtained by halocyclizing bis-silylimidate or mono-silylimidate of the bicyclic urea.

Abstract:
The online shopping has been much easier and popular, and meanwhile brings new challenges and opportunities to the field of product design and marketing sale. On one hand, product manufacturers find it challenging to produce new popularly accepted products to meet the customers’ needs; on the other hand, end customers usually feel it difficult to buy ideal goods that they really want, even if navigating a huge amount of commodities. There are indeed a ‘communication gap’ between the customers and manufacturers. As an effort to partially resolve the issue, this paper proposes a novel product synthesis approach from ‘voice of the customer’ over product knowledge graphs. Here the voice of customers mainly refer to the buyers’ product reviews from online shopping platforms or blogs, while the product knowledge graph is constructed containing professional hierarchical product knowledge on its properties based on ontological models. Using the technologies of natural language processing, we first extract the customs’ polarities on each specific aspect of a product, which are then transited to design requirements on the product’s design components. Based on the requirement extractions, and the pre-built product knowledge, semantic web and reasoning techniques are utilized to synthesize a novel product that meets more customer needs. Typical case studies on mobile phones from raw online data demonstrate the proposed approach’s performance.

Abstract:
The general objective of this BARD project focused on rationally designed insect neuropeptide (NP) agonists and antagonists, their application for the characterization of the mechanisms of action of the pyrokinin/PBAN (PK-PBAN) family and the development of biostable, bioavailable versions that can provide the basis for development of novel, environmentally-friendly pest insect control agents. The specific objectives of the study, as originally proposed, were to: (i) Test stimulatory potencies of rationally designed backbone cyclic (BBC) peptides on pheromonotropic, melanotropic, myotropic and pupariation activities; (ii) Test the inhibitory potencies of the BBC compounds on the above activities evoked either by synthetic peptides (PBAN, LPK, myotropin and pheromonotropin) or by the natural endogenous mechanism; (iii) Determine the bioavailability of the most potent BBC compounds that will be found in (ii); (iv) Design, synthesize and examine novel PK/PBAN analogs with enhanced bioavailability and receptor binding; (v) Design and synthesize ‘magic bullet’ analogs and examine their ability to selectively kill cells expressing the PK/PBAN receptor. To achieve these goals the agonistic and antagonistic activities/properties of rationally designed linear and BBC neuropeptide (NP) were thoroughly studied and the information obtained was further used for the design and synthesis of improved compounds toward the design of an insecticide prototype. The study revealed important information on the structure activity relationship (SAR) of agonistic/antagonistic peptides, including definitive identification of the orientation of the Pro residue as trans for agonist activity in 4 PK/PBANbioassays (pheromonotropic, pupariation, melanotropic, & hindgut contractile) and a PK-related CAP₂b bioassay (diuretic); indications that led to the identification of a novel scaffold to develop biostbiostable, bioavailable peptidomimetic PK/PBANagonists/antagonists. The work led to the development of an arsenal of PK/PBAN antagonists with a variety of selectivity profiles; whether between different PKbioassays, or within the same bioassay between different natural elicitors. Examples include selective and non-selective BBC and novel amphiphilic PK pheromonotropic and melanotropic antagonists some of which are capable of penetrating the moth cuticle in efficacious quantities. One of the latter analog group demonstrated unprecedented versatility in its ability to antagonize a broad spectrum of pheromonotropic elicitors. A novel, transPro mimetic motif was proposed & used to develop a strong, selective PK agonist of the melanotropic bioassay in moths. The first antagonist (pure) of PK-related CAP₂b diuresis in flies was developed using a cisPro mimetic motif; an indication that while a transPro orientation is associated with receptor agonism, a cisPro orientation is linked with an antagonist interaction. A novel, biostablePK analog, incorporating β-amino acids at key peptidase-susceptible sites, exhibited in vivo pheromonotropic activity that by far exceeded that of PBAN when applied topically. Direct analysis of neural tissue by state-of-the-art MALDI-TOF/TOF mass spectrometry was used to identify specific PK/PK-related peptides native to eight arthropod pest species [house (M. domestica), stable (S. calcitrans), horn (H. irritans) & flesh (N. bullata) flies; Southern cattle fever tick (B. microplus), European tick (I. ricinus), yellow fever mosquito (A. aegypti), & Southern Green Stink Bug (N. viridula)]; including the unprecedented identification of mass-identical Leu/Ile residues and the first identification of NPs from a tick or the CNS of Hemiptera. Evidence was obtained for the selection of Neb-PK-2 as the primary pupariation factor of the flesh fly (N. bullata) among native PK/PK-related candidates. The peptidomic techniques were also used to map the location of PK/PK-related NP in the nervous system of the model fly D. melanogaster. Knowledge of specific PK sequences can aid in the future design of species specific (or non-specific) NP agonists/antagonists. In addition, the study led to the first cloning of a PK/PBAN receptor from insect larvae (S. littoralis), providing the basis for SAR analysis for the future design of 2ⁿᵈgeneration selective and/or nonselective agonists/antagonists. Development of a microplate ligand binding assay using the PK/PBAN pheromone gland receptor was also carried out. The assay will enable screening, including high throughput, of various libraries (chemical, molecular & natural product) for the discovery of receptor specific agonists/antagonists. In summary, the body of work achieves several key milestones and brings us significantly closer to the development of novel, environmentally friendly pest insect management agents based on insect PK/PBANNPs capable of disrupting critical NP-regulated functions.

Abstract:
In this work, the power of the calculated electric rocket engine (ERE) requires thrust, specific impulse, and efficiency. ERE thrust measurement is interesting enough to achieve smallness of rapid growth. Specific impulse and efficiency are measured using laboratory methods. For this reason, one should naturally approach the choice of design parameters and the composition of the measuring system. One of the synthesis products can be the minimization of measurement errors. The paper approaches an approach to a priori instrumental estimation of the error determination, which may be useful in the synthesis of a system measurement of the ERE characteristics.

Abstract:
Remote sensing using Synthetic Aperture Radar (SAR) offers powerful methods for monitoring ground deformation from both natural and anthropogenic sources. Advanced analysis techniques such as Differential Interferometric Synthetic Aperture Radar (DInSAR), change detection, and Speckle Offset Tracking (SPO) provide sensitive measures of ground movement. With both the RADARSAT-2 and RADARSAT Constellation Mission (RCM) SAR satellites, Canada has access to a significant catalogue of SAR data. To make use of this data, the Canada Centre for Mapping and Earth Observation (CCMEO) has developed an automated system for generating standard and advanced deformation products from SAR data using both DInSAR and SPO methods. This document provides a user guide for this automated processing system.
