A general and versatile method for the divergent and diastereoselectivesynthesis of polyhydroxylated indolizidines has been established. The annulation reactions of a readily available enantiopure dihydroxylated cyclic secondary enamine with α,β-unsaturated carboxylates including methyl acrylate, methyl crotonate, methyl 2-hexenoate, allenoate, and dimethyl acetylenedicarboxylate and with malonyl
