Abstract
A 2,3-epoxy-1-alkanol (obtained by Sharpless asymmetric epoxidation of the corresponding allylic alcohol), O-protected with a 2-methoxypropy l group, undergoes highly regioselective oxirane ring opening by attac k of azide ion at C-3 to afford a monoprotected azidodiol which can be elaborated to divergently give either threo-or erythro-3-azido- 1,2-e poxide. An application to the synthesis of the natural amino acid stat ine, 24, and of its 3-epimer, 26, is described.
