Stereoselective synthesis of a new chiral synthon: a cyclic pseudodipeptide containing an aspartic acid derivative and l-valine

A simple stereoselective synthesis of cyclic synthons 4a,b and 10a,b, derived from an l-valine unit and an unnatural derivative of the aspartic acid, has been accomplished starting from the chiral synthon 1 and following the procedure already reported by
