METHODOLOGY DEVELOPMENT OF N-SULFINYL METALLOENAMINES AND ASYMMETRIC TOTAL SYNTHESIS OF (+)-EPIIBOGAMINE
… focuses on methodology development using N-sulfinyl metallodienamines and metalloenamines derived from Davis-Ellman N-sulfinyl imines. The application of these methodologies toward the total syntheses of (+)-epiibogamine and (+)-chimonanthine is described. The vinylogous aldol reaction of …

Asymmetric Synthesis of 1,3-Amino Alcohols and Tropinone Derivatives From Enantiopure Sulfinimines
… and tropane-containing derivatives using sulfinimines (N-sulfinyl imines) as precursors for acid-catalyzed cascade cyclizations. Chiral N-sulfinyl b-amino ketones derived from N-sulfinyl b-amino Weinreb amides, serve as novel and direct precursors to syn and anti N-sulfinyl 1,3-amino alcohols …

Asymmetric Synthesis of Homotropinone and Tropane Alkaloids using Enantiopure Sulfinimines and the Synthesis and Applications of Methanoprolines
… 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 synthesis of substituted homotropinone alkaloids from enantiopure …
