A Short Stereocontrolled Synthesis of Hydroxyethylene Dipeptide Isosteres

A stereocontrolled synthesis of protected hydroxyethylene dipeptide isosteres 14 and 16 is described.It provides the 2R,4S,5S epimers required for the preparation of aspartic proteinase inhibitors.The choice of a benzene ring as a precursor to the carboxy
