The invention includes selected novel optically active &agr;-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.
本发明包括精选的新型光学活性&agr;-
氨基酮,其本身是有用的,或者是制备用作抗生素、抗生素增强剂或酶
抑制剂的已知亚酮假肽的中间体。此外,本发明还提供了一种脱氢/不对称氢化方法,以获得具有两个手性中心的基本纯的反义亚甲基伪肽。
