N-Substituted Pyrrolidin-3-ones as Heterocyclic Building Blocks. Enantioselective Synthesis of 8-Epi- and 1,8,8a-Triepi-castanospermine

Regioselective aldol reaction of dianion 1 with aldehyde 5 provides the basis of a new approach to the construction of polyhydroxy indolizidines and the application of this methodology to the synthesis of 8-epicastanospermine 11 and 1,8,8a-triepicastanosp
