Texto completo2,2'-Bipyridines and their appropriate N,N'-dioxides form a significant class of heteroaromatic compounds, which has found application in various fields of chemistry and predominantly in asymmetric catalysis. One of the most powerful methods for their synthesis is cocyclotrimerization of alkynes with nitriles.A new variant of cyclotrimerization reaction – cocyclotrimerization of halodiynes with nitriles, which results in the formation of 2- and 3-halopyridines, has been developed. The reaction was studied on a wide range of substrates providing the pyridine products in good isolated yields. Formation of an unexpected product of halogen exchange reaction was observed during the course of the study and its origin was elucidated by experimental studies.The prepared 2-halopyridines were used as starting materials for syntheses of new chiral 2,2'-bipyridine ligands. The crucial step of their synthesis turned out to be the reductive dimerization of 2-halopyridines to the corresponding 2,2'-bipyridines. Application of the formed bipyridine ligands was then tested in various metal-catalyzed asymmetric reactions, namely Mukaiyama aldol reaction, hydroxymethylation, conjugate addition, C–H activation of indole and desymmetrization of meso-epoxides, in which one of the bipyridine ligands showed extraordinary activity and robustness. The structural properties of this ligand were then studied based on the NMR analyses, DFT calculations and single crystal X-ray analyses.New axially chiral 2,2'-bipyridine N,N'-dioxides were synthesized via two approaches, which differed in the type of the key dimerization step. While the first approach, based on the reductive dimerization of 2-halopyridines, furnished only one atropoisomer of the target N,N'-dioxide by an eight-step reaction sequence, the second approach, based on oxidative dimerization of pyridine-N-oxides, provided both atropoisomers in only five steps. The applicability of these novel N,N'-dioxides as Lewis base catalysts were then examined in the enantioselective allylation of benzaldehyde and aldol reaction of trichlorosilyl ketene acetal with acetophenone

Texto completo: Recent developments in green and sustainable science require more powerful, sophisticated and tunable catalysts. Bimetallic catalysts contain two or more sites for the activation of substrates and, under optimal circumstances, can allow cooperative activation of reacting substrates on neighboring metal centers. A number of backbones, designed specifically to generate exclusively bimetallic complexes have previously been developed around methanodibenzodioxocin and benzofurobenzofuran scaffolds, including a number of ligands that act as monophosphine donors to two different metal centers. These ligands generate dinuclear species reliably, but the resulting coordination modes are unpredictable. This work presents the synthesis of tetraphosphine ligands, wherein chelating arms are available to coordinate each of the two metal centers. The synthesis involves preparation of 4,8-bis(sec-phosphines) of rac- 6,12-methano-12H-dibenzo[l,3] dioxocins and their conversion into doubly chelating phosphines through the elaboration of each sec- phosphine functionality into the corresponding di(R)phosphinopropyl derivatives (R= Ph, Cy). A preliminary coordination chemistry study indicates that the tightly defined coordination environment provided by these rigid binucleating tetraphosphine ligands under study allowed bimetallic complexes of PdII, PtII to be prepared, in which each of the two chelating arms molecule coordinates to one metal. Finally outline studies on the use of the tetraphosphine ligands as supports for hydroformylation chemistry were performed. The current results do not yet allow cooperative behavior between the two metal centers to be definitively established

Texto completoPh.D.
Muscarinic receptors are G-protein-coupled receptors that mediate the response to acetylcholine released from parasympathetic nerves. Although five mAChR subtypes (M1-M5) share a high degree of homology, they display different physiological effects including controlling smooth muscle tone to neurotransmitter release in the CNS. Hence these receptor subtypes have been investigated as potential therapeutic targets for agents capable of treating Alzheimer's Disease, Parkinson's Disease, peptic ulcer disease, COPD, urinary incontinence, and muscle spasms. Our interest in the development of subtype selective muscarinic ligands led to previous reports detailing the identification of substituted lactones as lead muscarinic compounds. Later work involved molecular modifications of those leads that included the addition of aromatic groups with a variety of substitution patterns. These efforts led to an increase in receptor affinity and produced a lactone-based muscarinic ligand with an IC50 of 340nM. As a continuation of that work, additional novel ligands were designed based on the general pharmacophoric elements proposed for the lactone-based ligands. In that model, the lactone oxygens serve as H-bond acceptor moieties while different nitrogen containing heterocycles provide the requisite cationic group. These groups may be separated by linker groups of varying sizes. In order to synthesize the lactone-based ligands mentioned above, efficient synthetic routes are required for key precursors. These include but are not limited to: 1. A novel high yield synthesis of the hydroxyethyl-lactone precursor was designed using a carefully controlled Prins reaction. The method readily quenches a cationic intermediate and simultaneously protects hydroxyl groups in a single step. A mechanism for the new route to the precursor is proposed and its use in the preparation of the target compounds is presented 2. Microwave-assisted synthesis of various sterically hindered N-aryl piperazines has been developed allowing quick access to structurally diverse muscarinic ligands These synthesis along with other newly developed routes enabled ready access to 59 novel muscarinic ligands. The ligands were tested in a general muscarinic binding assay. The result was analyzed and SAR study was performed to direct ligand design. As a result of this work, ligand affinity was improved by over 100 folds compare to the lead molecules. Several promising compounds were selected and selectivity tested.
