A short and highly stereocontrolled total synthesis of (3R,5R,8aR)-3-n-Butyl-5-methylindolizidine

Total synthesis of (-) (3R,5R,8aR)-3-n-Butyl-5-methylindolizidine is described in 9 steps (22% overall yield) from L-proline.

Synthesis of indolizidines (-)-195B, (-)-223AB and (-)-239AB: (2S,5R)- l-[(benzyloxy)carbonyl]-2-methoxycarbonyl-5-(4pentenyl)pyrrolidine as a versatile chiral building block

The total syntheses of three levogyre 3,5-disubstituted indolizidines, (-)-195B, (-)-223AB and (-)-239AB are described. The employed strategy is based on the utilization of the common enantiopure trans 2,5-disubstituted pyrrolidine 3, which is assembled b
