Full details are given for the syntheses of the protease inhibitors, poststatin and eurystatin by the acyl cyanophosphorane coupling procedure used for the formation of α-keto amides. We have also extended this methodology to the syntheses of the related α-hydroxy amide natural products, phebestin, probestin and bestatin. The key step in the latter synthetic sequences involved diastereomeric selectivity
通过用于形成α-酮酰胺的酰基氰基磷膦偶联方法,给出了蛋白酶抑制剂poststatin和eurystatin的合成的全部细节。我们还将这种方法扩展到了相关α-羟基酰胺天然产物phebestin,probestin和bestatin的合成中。后一合成顺序中的关键步骤涉及通过使用硼氢化锌将α-酮基前体还原为相应的α-羟基酰胺的非对映异构体选择性。
