Abstract:

As a part of our studies on asymmetric induction, four topics were investigated in this thesis. Firstly, optically active menthyl and neo-menthyl phos-phonoacetates were prepared and the reaction of their anions with aldehydes and ketones studied, modest asymmetric induction was observed. A chiral phosphonamide anion was also synthesised which shows good selectivity on reaction with ethyl bromide. Secondly, the reactions of aldehydes and ketones with chiral organolithium compounds were investigated. The best results were obtained with a chiral lithiated dithiane, when a ratio of (1:1.9) was ob

Abstract:

Direct generation of enantioenriched mono-α-alkylated aldehydes by intermolecular nucleophilic substitution is a general and long-standing problem in synthesis, and is of importance due to the diverse reactions such aldehydes undergo for introducing asymmetry into molecules. The work described in this thesis initially details the development of the first lithium amide capable of efficiently converting terminal epoxide into enamine functionality, where the latter also demonstrates effective C-alkylation activity. Not only addition to Michael acceptors, but more notably substitution using activa

Abstract:

Crystallization-induced diastereoisomer transformation (CIDT) was successfully employed in the enantioselective synthesis of 2-alkyl-3-aryl-propan-1-amines. These products are seen as potentially useful building blocks in the field of asymmetric organic chemistry, notably for pharmaceutically relevant compounds. The procedure was based on a recently reported protocol for deracemization of dihydrocinnamic aldehydes in which enantiomerically enriched 1-(amino(phenyl)methyl)naphthalen-2-ol (Betti base) is employed as a resolving agent. Additionally, fenpropimorph, a biologically active substance

Abstract:

This thesis deals with method development in asymmetric catalysis and specifically syntheses of enantioenriched O-functionalized cyanohydrins. The first part describes the development of a method for the synthesis of O‑alkoxycarbonylated and O-acylated cyanohydrins. Ethyl cyanoformate and acyl cyanides were added to aldehydes in a reaction catalyzed by a chiral dimeric Ti-salen complex together with a tertiary amine. High yields and enantioselectivities were in most cases obtained. Mechanistic studies were performed and a reaction mechanism was proposed. The second part describes a method in

Phosphorus is an element that is essential for life, and is used in the synthesis of many proteins, carbohydrates and deoxyribonucleic acids. Phosphorus often exists in the form of phosphate when found in the biological systems. Clinical development of possible pharmaceutical agents have used phosphorus in the form of phosphonates to increase the metabolic stability of the potential drug. Some of these phosphonates target the isoprenoid biosynthetic pathway (IBP). The IBP plays an important role in the synthesis of cholesterol and in other aspects of cellular metabolism.

Rotaxanes are a class of compounds composed of two or more mechanically interlocked molecules. Mechanically planar chiral rotaxanes are a novel class of compound in that their chirality is due to the isomerism of a mechanical bond, as opposed to the covalent bonding of the individual components. We know of no method to synthesise enantiomerically pure samples of the mechanical isomers of a mechanically planar chiral rotaxane without resorting to advanced purification techniques.
