This work demonstrates an effective and green synthetic strategy for the preparation of quinoxalines utilizing sulfoxonium ylides as safe carbene sources via a key N–H insertion. The method was also applied to S–H insertions for synthesis of β‐keto thioethers under mild and economical conditions. This strategy avoids the safety issues of diazo compounds and the use of organic solvents, which meets
这项工作证明了通过关键的N–H插入,利用sulf基亚砜作为安全的卡宾来源制备
喹喔啉的有效和绿色合成策略。该方法还适用于在温和且经济的条件下合成β-酮
硫醚的S–H插入物。该策略避免了重氮化合物的安全性问题和有机溶剂的使用,从而满足了可持续
化学的要求。
