摘要

Abstract An efficient synthesis of (6R, 7R, 8S, 8aS)-6, 7, 8-trihydroxyindolizidine and (6R, 7R, 8R, 8aS)-6, 7, 8-trihydroxyindolizidine is described from readily available N-BOC-L- proline,(BOC= tert-butoxycarbonyl) which involves the addition of ethyl lithiopropiolate to the aldehyde derived from N-BOC-L-proline as a key step, then cyclization to construct indolizidine skeletons and asymmetric dihydroxylation.(© Wiley-VCH Verlag GmbH & Co. ...
