G. Righi et al., A SIMPLE ROUTE TO SYN ALPHA-AMINO-BETA-HYDROXY ESTERS BY C-2 REGIOSELECTIVE OPENING OF ALPHA,BETA-EPOXY ESTERS WITH METAL-HALIDES, Tetrahedron, 51(48), 1995, pp. 13401-13408
alpha,beta-Epoxy esters are opened by NaX (X = I, Br) in a regio and s
tereoselective fashion to beta-hydroxy-alpha-halo esters, which repres
ent suitable precursors of syn alpha-amino-beta-hydroxy esters and bet
a-hydroxy esters.
