efficient strategy for the preparation of medium-size-ring sulfonyl derivatives has been developed. This method is realized by alkynes insertion into the C–C σ-bond of cyclic β-keto sulfones, introducing sulfonyl groups into medium-size-ring compounds. This reaction possesses competitive features such as broad substrate scope, transition-metal-free and atom economy.
已经开发了一种新型的碱促进和高效的制备中等尺寸环磺酰基衍
生物的策略。该方法是通过将
炔烃插入环状 β-
酮砜的 C-C σ-键中,将磺酰基引入到中等大小的环状化合物中来实现的。该反应具有底物范围广、不含过渡
金属、原子经济等竞争特点。
