摘要

我们开发了一种新颖简洁的方法来全合成用于治疗低钠血症的()托伐普坦。关键中间体苯并氮杂卓酮的合成分为三个步骤,首先是丙戊酰胺保护芳基胺的酰化反应,然后是分子内卤胺环化反应。以-氯苯胺为原料,通过七个步骤合成了()托伐普坦,总收率为 43%。

A novel approach for the synthesis of (S)-tolvaptan and (S)-desmethyltolvaptan

A novel approach for the synthesis of (S)-tolvaptan and (S)-desmethyltolvaptan

A novel and concise approach has been developed for the total synthesis of (S)-tolvaptan, which is used for the treatment of hyponatremia. The key intermediate, benzazepinone has been synthesized in three steps through ortho-acylation of N-Pivalamide protected aryl amine followed by an intramolecular haloamine cyclization. The total synthesis of (S)-tolvaptan from p-chloroaniline has been accomplished in seven steps with 43% overall yield.
