A total synthesis of the optically active 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 of a variety of N ‐[(benzyloxycarbonyl)methyl]tetrahydroesterastin β‐lactam analogues ( Scheme 5 ).
