A full account of the total syntheses of proteasome inhibitors TMC-95A and -B is provided. A key feature of the syntheses involved installation of a cis-propenylamide moiety by a thermal rearrangement of an alpha-silylallyl amide. The scope and mechanism of the enamide-forming reaction are discussed. Also provided are some preliminary results from SAR studies. It was found that simplified analogues
提供了蛋白酶体抑制剂 TMC-95A 和 -B 的全合成的完整说明。合成的一个关键特征涉及通过α-甲硅烷基烯丙基酰胺的热重排安装顺式丙烯酰胺部分。讨论了烯酰胺形成反应的范围和机理。还提供了一些 SAR 研究的初步结果。发现简化的类似物可以保留蛋白酶体抑制的全部效力。
