Synthesis of nitrogen containing heterocycles [PDF]
This thesis is concerned with the development of synthetic methodology for the synthesis of nitrogen containing heterocycles, specifically 2,5-disubstituted pyrrolidines, 2,6-disubstituted piperidines and 3,5-disubstituted indolizidines. Chapter 1 introduces current methods for the formation of 3,5-disubstituted indolizidines.
