A practical two‐stage one‐pot synthesis of N‐substituted β‐amino alcohols using aldehydes and isocyanides as starting materials has been developed. This method features mild reaction conditions, broad scope, and general tolerance of functional groups. Based on a less common central carbon–carbon bond disconnection, this protocol complements traditional approaches that involve amines and various carbon
已经开发出一种实用的两步法一锅法合成N-取代的β-氨基醇,该方法以醛和异氰酸酯为起始原料。该方法的特点是反应条件温和,范围广,对官能团的耐受性强。该协议基于较少见的中心碳-碳键断开连接,对涉及胺和各种碳亲电试剂(环氧化物,α-卤代酮,β-卤代醇)的传统方法进行了补充。如有关抗哮喘药沙丁胺醇的合成所示,可以从简单的结构单元中以简洁有效的方式制备药用相关产品。将合成物升级为对映选择性变体也是可行的。
