Book Description :

This thesis consists of two parts. Part One concerns the total synthesis of (±)-daurichromenic acid and a series of structural analogues. Daurichromenic acid, a natural product isolated from the leaves and twigs of Rhododendron dauricum, has potent anti-HIV activity. A concise synthetic route was designed whereby the target module was prepared in four steps from trans,trans-farnesal, ethyl crotonate and ethyl acetoacetate. Furthermore, the modular nature of the synthetic route allowed for the preparation of a variety of structural analogues of the natural produce. Although the overall yield of this route was relatively low, significant quantities of analytically pure materials have been obtained for subsequent biological evaluation. Two alternative routes were explored in order to circumvent a problematic dehydrogenation/aromatization step encountered in this route. In these instances, attempts were made to install the aromatic ring of the target compound through micration of a carbon-carbon dougle bond and via a retro-Diels-Alder reaction. Moreover, a strategy employing a phenylboronic acid-promoted condensation reaction of methyol orsellinate and +, -unsaturated aldehydes as the key step was also developed. This provided additional access to a series of structural analogues of (±)-daurichromenic acid from commercially available starting materials. In Part Two of the thesis a new procedure for the mono-dealkylation of tertiary amines is described. Attempted oxidation of a known hydroxy crown ether derivative, 2,3,9,10-dibenzo-6-hydroxy=16-crown-5, under modified Swern conditions resulted in the unexpected formation of a diethylamide as the major reaction product. Based on this initial observation, a novel and facile means was developed for the mono-dealkylation of a series of tertiary amines using a monoester of oxalyl chloride as the cleaving agent. The experiments also demonstrated that various alkyl groups could be cleaved and the selectivity of the bond breaking process was: benzy>ally1>methyl>hetrocyclic ring. The chemoselectivity of this new dealkylation procedure was demonstrated by performing the selective removal of the N-benzyl group of (2S)-1-benzyl-2-[(benzyloxy)methyl]pyrrolidine. The reaction proceeded cleanly and resulted in the isolation of the desired amide product in 83% yield. Subsequent hydrolysis of the amide product afforded (2S)-2[(benzyloxy)methyl]pyrrolidine in excellent yield.

Book Description :

The polyamines are ubiquitous and essential organic cations in prokaryotic and eukaryotic cells. This book is a comprehensive survey of the development of knowledge of their physiological and structural roles. Currently, the genetic and regulatory determinants of the amines and their cellular composition are being explored actively as parameters of normal physiology and aberrant pathologies. Cancer, virus infection, and protozoan parasitism are major examples of the later groups. Studies of the control of polyamine metabolism are providing important therapeutic leads. Further, the structural roles of the amines are being determined at molecular levels, contributing to the understanding of polynucleotide and protein organization and interaction, as well as to the solution of problems of genome transfer. These subjects describe a burgeoning biochemical area involving compounds whose roles in cytoplasmic and nuclear function include numerous aspects of organelle structure, polymer synthesis, and interactions.
