A new method of synthesis of cyclic imino acids is reported.Diastereoselective alkylation of Schiff bases (derived from α-amino esters and (+) or (-) 2-hydroxypinan-3-one) with dihalogeno compounds, followed by hydrolytic cleavage and cyclization affords the imino esters.Reactions are highly enantioselective, with one exception corresponding to steric crowding.
