Abstract (sommario):

Abstract: Because of their synthetic challenge, broad range of physical I chemical properties, and diverse biological activities, heterocycles continue to be of interest to both the academic and industrial chemist. This review covers recent advances in the solid phase synthesis of drug-like heterocyclic small molecules. Syntheses which form the heterocycle on the solid phase are emphasized; syntheses in which a preformed heterocycle is functionalized on the solid support have been omitted. The majority of references are from publication year 1999. This review should be of interest to anyone involved in, or contemplating the solid phase synthesis of small molecule drug-like heterocycles, especially for combinatorial chemistry applications.

Abstract (sommario):

Background: 1,4-Dithiane-2,5-diol (1,4-DTD) is the stable dimer of α-mercapto acetaldehyde. This commercially available ambidentade compound is characterized as having in its chemical structure one group that acts as an electrophile and another that acts as a nucleophile, this permits its use as versatile and efficient synthon in synthetic heterocycle procedures. Objective: The aim of this review is to present synthetic applications of 1,4-DTD in heterocyclic chemistry and their applicability to the synthesis of bioactive compounds. Conclusion: Gewald reactions to obtain C-4 and C-5 unsubstituted 2-amino-thiophene derivatives; sulfa- Michael/Henry and sulfa-Michael/aldol sequences to obtain polysubstituted tetrahydrothiophenes, and other heterocyclic reactions that allow synthesizing several functionalized sulfur-containing heterocycles such as thiazolidines, oxathiazinoles and thiazoles are presented and discussed. The use of such heterocyclics in subsequent reactions allows obtaining various bioactive compounds including the antiretroviral lamivudine which is one of the examples presented in this review.

Abstract (sommario):

There is compelling evidence that incorporating a heterocyclic moiety into a steroid can alter its pharmacological and pharmacokinetic properties, driving intense interest in the synthesis of such hybrids among research groups. In this review, we present an overview of recent synthetic methodologies, spanning the period from 2000 to 2023, for the preparation of spiro heterocyclic steroids. The compounds surveyed encompass four-, five-, six-, and seven-membered heterocycles appended to various positions of steroidal backbones, with spirocycles containing oxygen, nitrogen, and sulfur atoms being predominant. The outlined synthetic procedures emphasize the pivotal steps for constructing the heterocycles, often accompanied by a detailed account of the overall synthesis pathway. The review encompasses innovative compounds, including bis-steroids linked by a spiro heterocycle and steroids conjugated to heterocyclic moieties containing three or more (hetero)cycles. Moreover, many compounds are accompanied by data on their biological activities, such as antiproliferative, antimalarial, antimicrobial, antifungal, steroid antagonist, and enzyme inhibition, among others, aimed at furnishing pertinent insights for the future design of more potent and selective drugs.

Abstract (sommario):

The chemistry of heterocyclic compounds has traditionally been and remains a bright area of chemical science in Russia. This is due to the fact that many heterocycles find the widest application. These compounds are the key structural fragments of most drugs, plant protection agents. Many natural compounds are also derivatives of heterocycles. At present, more than half of the hundreds of millions of known chemical compounds are heterocycles. This collective review is devoted to the achievements of Russian chemists in this field over the last 15–20 years. The review presents the achievements of leading heterocyclists representing both RAS institutes and university science. It is worth noting the wide scope of the review, both in terms of the geography of author teams, covering the whole of our large country, and in terms of the diversity of research areas. Practically all major types of heterocycles are represented in the review. The special attention is focused on the practical applications of heterocycles in the design of new drugs and biologically active compounds, high-energy molecules, materials for organic electronics and photovoltaics, new ligands for coordination chemistry, and many other rapidly developing areas. These practical advances would not be possible without the development of new fundamental transformations in heterocyclic chemistry.<br> Bibliography — 2237 references.

Abstract: Heterocyclic chemistry is very important aspects in organic chemistry. Heterocyclic system consists of one or more heteroatoms like nitrogen, oxygen, sulphur, etc with hydrogen atoms. The system can be classified as saturated as well as non saturated system or hydrocarbons. Another classification of this ring system is divided in some categories like three-membered, four-membered, five-membered, six-memebered, seven-membered, fused heterocyclics etc. Some compounds under this cklassification are acidic or basic in nature. Examples of heterocyclic compounds are Pyrole, Furan, Thiophene, Pyridine, Quinoline, Isoquinoline, Indole, Purine, Pyrazole, etc. Pyrazole is very important under this heterocyclic ring sysyem. Pyrazole is five membered heterocyclics. Pyrazole is basic and unsaturated in nature due to presence of double bonds in their ring structure. When two nitrogen atoms are associated with five menbered heterocyclic ring in 1,2 positions called as Pyrazole structure. It is also known as 1,2-diazole. It is present in many drugs as well as organic compounds and Pharmaceutical compounds.

Abstract (sommario):

Background: The chemists have been interested in light as an energy source to induce chemical reactions since the beginning of the scientific chemistry. This review summarizes the chemistry of photochemical reactions with emphasis of their synthetic applications. The organic photochemical reactions avoid the polluting or toxic reagents and therefore offer perspectives for sustainable processes and green chemistry. In summary, this review article describes the synthesis of a number of six-membered O-heterocycles. Objective: Photochemistry is indeed a great tool synthetic chemists have at their disposal. The formation of byproducts was diminished under photochemical substrate activation that usually occurred without additional reagents. Photochemical irradiation is becoming more interesting day by day because of easy purification of the products as well as green chemistry. Conclusion: This review article represents the high applicability of photochemical reactions for organic synthesis and research activities in organic photochemistry. The synthesis of heterocyclic molecules has been outlined in this review. Traditional approaches require expensive or highly specialized equipment or would be of limited use to the synthetic organic chemist due to their highly inconvenient approaches. Photochemistry can be used to prepare a number of heterocycles selectively, efficiently and in high yield.

Abstract (sommario):

Chapter One reviews the use of scandium and lanthanide trifluoromethanesulfonates (triflates) in organic synthesis. Their ability to act as Lewis acids and so promote a wide variety of reactions are illustrated. In particular the review highlights the advantages of scandium and lanthanide triflates over more conventional Lewis acids, such as aluminium(I1I) chloride. Chapter Two describes the use of scandium and lanthanide trifiates in the reaction of acetals with amines to produce imines. The extension of this methodology to the synthesis of nitrogen-containing heterocycles such as isoindolones, isoquinolinones and ~-carboline derivatives are elaborated on. Some limitations of the methodology and the problems encountered with its application to the synthesis of enamines are covered. Chapter Three reports our approach to a novel synthesis of ~-carboline derivatives. The formylation of indole-3-acetic acid derivatives in the 2- position proved difficult and several approaches to this problem are discussed. The attempted cyclisation of imines prepared from 2-formyl- and 2- acetyl-3-indolyl acetic acid compounds are also covered. Chapter Four describes a modified Clauson-Kaas pyrrole procedure using trimethylsilyl trifiate. The selection of reaction conditions in an effort to optimise the procedure are discussed. Chapter Five provides full experimental procedures and analytical data for the reactions described in Chapters Two, Three and Four.

Testo completo

Abstract (sommario):

In this project the use of amides as precursors for imidoyl radicals in heterocyclic chemistry has been developed. Amides were converted to thioamides, which function as precursors for imidoyl radical equivalents. Also, a novel protocol for the synthesis of imidoyl selanides was developed for the purpose of using these as imidoyl radical precursors. The precursors were used in a study of intramolecular oxidative cyclisation of imidoyl radicals onto electron deficient pyrroles and indoles. The imidoyl radical equivalents derived from thioamides did not cyclise onto heteroarene double bonds. In contrast, imidoyl radicals derived from imidoyl selanides did cyclise 6-exo onto activated heteroarenes, but yields were generally low due mainly to competing reduction of the imidoyl radical, but also due to adduct formation with isobutyronitrile radicals originating from the initiator.
