[reaction: see text] In this, the first of two letters, we outline the use of the pyrrolidine-5,5-trans-lactam template to design small, neutral, mechanism-based inhibitors of hepatitis C NS3/4A protease. The hitherto unreported reaction of the acyl iminium ion precursor 4 with dialkyl-substituted silyl ketene acetals (e.g., 8b) is described. Compound 12b, with a spirocyclobutyl P1 substituent and
[反应:参见正文]在此,我们以两个字母的第一个字母概述了吡咯烷5,5-反式内酰胺模板的用途,以设计小型,中性,基于机制的丙型肝炎NS3 / 4A蛋白酶抑制剂。描述了酰基亚胺离子前体4与二烷基取代的甲硅烷基烯酮缩醛(例如8b)的迄今未报道的反应。内酰胺氮上具有螺环丁基P1取代基和环丙基酰基取代基的化合物12b的ak(obs)/ I为400 M(-)(1)s(-)(1),并在基于复制子细胞的替代物中表现出活性HCV分析。
