Enantioselective synthesis of indolizidine and quinolizidine derivatives from chiral non-racemic bicyclic lactams

Chiral non-racemic bicyclic lactams 2b,c, derived from (R)- and (S)-phenylglycinol, were used in the enantioselective synthesis of (-)-lupinine and 5-epitashiromine, respectively. The efficiency of the synthesis relied on the high diastereoselectivities of formation and reduction of compounds 2b,c.
