We have developed a convergent and stereoselective synthesis of orally active renin inhibitor BILA 2157 BS. Three building blocks were used to generate the basic skeleton of the inhibitor. The key feature consisted of the late elaboration of the 2-amino-4-thiazolyl heterocycle from a vinylbromide precursor. The synthetic sequence, which required a total of 22 chemical steps, provided 0.6 kg of BILA 2157 BS in 7.3% overall yield.Key words: renin, inhibitor, peptidomimetic, stereoselective synthesis.
我们已经开发出一种具有收敛性和立体选择性的口服活性肾素抑制剂BILA 2157 BS的合成方法。使用了三种构建模块来生成抑制剂的基本骨架。关键特征是从乙烯溴化物前体中晚期修饰2-氨基-4-噻唑基杂环。这种合成序列总共需要22个化学步骤,提供了0.6公斤的BILA 2157 BS,总产率为7.3%。关键词:肾素、抑制剂、肽类模拟物、立体选择性合成。
