The efficient and flexible syntheses of 5,8-disubstituted indolizidine poisonous-frog alkaloids is described using a highly stereoselective Michael-type conjugate addition reaction as the key step. In this work, syntheses of the 5,8-disubstituted indolizidine poisonous-frog alkaloids (-)-231C, (-)-221I and the proposed structure for (-)-193E are reported.

The enantioselective synthesis of indolizidines (-)-203A, (-)-209B, (-)-231C, (-)-233D, and (-)-235B″ has been achieved and the absolute stereochemistry of both indolizidines 203A and 233D was established as 5S,8R,9S. The relative stereochemistry of natur
