描述了α-酰基氨基烷基1.1-二氟-3-丁烯基酮的合成。由α-氨基酸获得的取代的5(4H)-恶唑酮与2.2-二氟-4-戊烯酸酐(对于R 2 = C 6 H 5)或2.2-二氟-4-戊烯酰氯和4 -二甲基氨基吡啶/三乙胺[对于R 2 = CH 3,C 6 H 5,CH(CH 2 C 6 H 5)NHCO 2 CH 2 C 6 H 5而言],然后用无水草酸处理,得到目标结构。
This invention relates to analogs of peptidase substrates in which the amide group containing the scissile amide bond of the substrate peptide has been replaced by an activated electrophilic ketone moiety. These analogs of the peptidase substrates provide specific enzyme inhibitors for a variety of proteases, the inhibition of which will have useful physiological consequences in a variety of disease states.
