摘要：

Indolizidine 209D (2) was synthesized in 11 steps from L-aspartic acid (3) in an overall yield of 16%. 3R-pyrrolylnonanoic acid, prepared from 3, was converted into the alpha-keto diazomethyl derivative, which on Rh2(OAc)4-catalyzed cyclization and catalytic hydrogenation gave 2. A similar procedure, starting from 3, afforded 3R-pyrrolyl-hexanoic acid, an intermediate which had prevoiusly been converted in 3 steps to indolizidine 167B.
