Alkaloid syntheis via novel azabicycles.
A basic introduction to pyrrolizidine and indolizidine alkaloids has been described along with a selection of recent syntheses of the said compounds.Cycloalkene synthesis by intramolecular Wittig reaction has been reviewed and we describe the utility of this strategy in the formation of …

Asymmetric Synthesis of Homotropinone and Tropane Alkaloids using Enantiopure Sulfinimines and the Synthesis and Applications of Methanoprolines
The development of new methodologies for the asymmetric synthesis of homotropinone and tropane alkaloids using enantiopure sulfinimines [RS(O)N=CR1R²] is the primary objective of this thesis. In one study a four-step intramolecular Mannich cyclization cascade reaction was devised for the asymmetric …
