A novel iron-catalyzed efficient approach to construct sulfone-containing oxindoles, which play important roles in the structural library design and drug discovery, has been developed. The use of readily available benzenesulfinic acids, an inexpensive iron salt as the catalyst, and air as the oxidant makes this sulfur incorporation protocol very efficient and practical.
一种新的铁催化的方法已被开发出来,用于构建含有砜结构的吲哚酮,这些吲哚酮在结构库设计和药物发现中扮演着重要角色。该方法采用易得的苯磺酸亚磺酸盐、廉价的铁盐作为催化剂,并利用空气作为氧化剂,使得这种硫掺入方案非常高效且实用。
