Ring-closing olefin metathesis using the Grubbs catalyst was applied to the cyclisative release of resin-bound sulfonamides. Flexible linkers apparently facilitated the cyclisation–cleavage, allowing a number of novel cyclic sulfonamides to be prepared in good yields using catalytic amounts of the Grubbs catalyst.
使用Grubbs催化剂的闭环烯烃复分解用于
树脂结合的磺酰胺的环化释放。柔性连接基显然促进了环化反应的裂解,从而可以使用催化量的Grubbs催化剂以高收率制备许多新型的环磺酰胺。
