ABSTRACT:
The invention includes selected novel optically active α-amino ketones which either are themselves useful or are intermediates for the preparation of known ketomethylene pseudopeptides useful as antibiotics, antibiotic enhancers, or enzyme inhibitors. Further, the present invention provides a method for dehydrogenation/asymmetrical hydrogenation to obtain essentially pure antipodes of ketomethylene pseudopeptides having two chiral centers.
