Methanolysis of N-acyl-thiazolidin-2-thiones and -oxazolidin-2-thiones in the presence of acyl transfer catalyst benzotetramisole (BTM) proceeds in a highly enantioselective fashion thus enabling kinetic resolution of these substrates.

A total synthesis of the opticallyactive tetrahydroesterastin β -lactam analogue 2 using Miller's hydroxamate approach is described (Scheme 2). Significant modification of published procedures has resulted in a short and facile stereospecific preparation of the N-[(benzyloxycarbonyl)methyl]-β -lactam 17 starting from the readily available D-serine. This material served as intermediate for the preparation
