Regiospecific ring-opening reactions of β-aziridinyl ct, β-enoates with acids: Application to the stereoselective synthesis of a couple of diastereoisomeric (Zi)-alkene dipeptide isosteres from a single β-aziridinyl a, β-enoate and to the convenient preparation of amino alcohols bearing a, β-unsaturated ester groups

Regio- and stereo-selective ring-opening reactions of N-(2, 4, 6-trimethylphenylsulfonyl)-γ, δ-cis- or trans-γ, δ-epimino (E)-α, β-enoates with acids such as methanesulfonic acid (MSA) or trifluoroacetic acid (TFA) have been found. These ring-opening reactions are useful for the stereoselective synthesis of a couple of diastereomeric (￡)-alkene dipeptide isosteres from a single substrate of γ, δ-epimino (E)-α, β-enoate, and for the convenient preparation of δ-aminated γ-hydroxy α, β-enoates.
