analog inhibitors of certain proteinases. Reformatsky reaction of aldehyde N-t-butyloxycarbonyl l-phenylalaninal (3), with bromodifluoromethylphenyl acetylene provided the key intermediate for the synthesis of a series of potent HIV proteinase inhibitors exemplified by 1.
许多α,α-二氟酮,例如2S-(N-苄氧基羰基-缬氨酸基)氨基-3-氧代-4,4-二氟-1,6-二苯基-己烷(1),强电负性氟紧挨着羰基,通常是完全水合的。由于羰基的水合,二氟酮可作为某些蛋白酶的过渡态类似物抑制剂。醛N-叔丁氧基羰基L-苯丙氨酸的Reformatsky反应(3)与溴二氟甲基苯基乙炔为合成一系列有效的HIV蛋白酶抑制剂(例如1)提供了关键的中间体。
