Book excerpt: This thesis is a summary of research conducted since October 1998 at the University of Toronto in the laboratory of Dr. Robert A. Batey. This manuscript is divided into two chapters. In chapter one, the synthesis of 5-aminotetrazoles ' via' the mercury promoted attack of azide anion on a thiourea is described. The reaction is applicable to mono-, di- and trisubstituted thioureas and represents the first general route to 5-aminotetrazoles of various substitution patterns. Chapter two describes progress towards the synthesis of martinelline, a novel hexahydropyrroloquinoline alkaloid containing three guanidine moieties. Application of the two and three component hetero Diels-Alder methodology is expanded to other dienophiles in attempts to construct the martinelline core 'via' a biomimetic approach. Finally the successful conversion of a tertiary thiourea 4-arylhexahydropyrrolo[3,2-c]quinoline to a guanidine is described for the first time within our labs.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of two parts. The first part describes the enantioselective total synthesis of martinellic acid. The Martinella alkaloids have attracted considerable attention in the synthetic community over the past few years. This interest is due in large part to their unique structure and useful biological activity (bradykinin receptor antagonist). In model systems we have successfully used the [3+2] azomethine ylide-alkene cycloaddition to construct the heterocyclic core of these alkaloids. The enantioselective approach described herein also involves the azomethine ylide-alkene cycloaddition as a key step in the total synthesis. The pyrrolo[3,2-c]quinoline core of this alkaloid was constructed in an enantioselective fashion by the elaboration of an N-aryl pyrrolidinone, which was obtained via Pd-catalyzed aryl amination reaction using a non-racemic lactam. Pirkle's chiral solvating agent was successfully used to demonstrate the stereochemical integrity of not only the N-aryl lactam (obtained by Pd-catalyzed cross-coupling) but also the cycloaddition precursor and the cycloaddition product (tetracyclic pyrroloquinoline core). The tetracyclic compound obtained via the azomethine ylide-alkene cycloaddition was elaborated to ( - )-martinellic acid in 11 steps and 6% overall yield. The second part of this dissertation describes application of several novel organometallic complexes for carrying out various organic transformations. A fluorinated tris(pyrazolyl)borato silver(I) complex catalyzes the addition of ethyl diazoacetate to benzene rings, providing norcaradienes, which undergo electrocyclization to provide the corresponding cycloheptatriene (the Bu & huml;chner reaction). These reactions are surprisingly selective for addition to the aromatic moiety rather than C-H insertion. A copper complex containing a fluorinated triazapentadienyl ligand has been used to catalyze some carbene and nitrene addition and insertion chemistry. Nitrene addition occurs rapidly and with both aryl and alkyl substituted olefins providing the corresponding aziridine. The carbene transfer reactions that were attempted include C-H insertion, O-H insertion and N-H insertion, of which the latter two were very efficient.
