Good migrations: The highly regioselective migration of a sulfonyl group for the synthesis of functionalized pyrroles is reported (see scheme; DMF=N,N‐dimethylformamide). The migration of the sulfonyl group to different positions can be controlled with high selectivity, thus allowing the formation of both α‐ and β‐(arylsulfonyl)methyl pyrroles with high yields.
良好的迁移:据报道,用于合成官能化吡咯的磺酰基具有高度的区域选择性迁移(参见方案; DMF = N,N-二甲基甲酰胺)。可以高选择性地控制磺酰基向不同位置的迁移,因此可以高产率地形成α-和β-(芳基磺酰基)甲基吡咯。
