In this work we report another method of acylation on the 6-position of the 2(3H)-benzothiazolone ring with Fries-like rearrangement catalyzed by zinc chloride instead of aluminium chloride and 3-acyl-2(3H)-benzothiazolones derivatives as starting materials. This method is advantagous in regard to other acylation methods as it requires only three equivalents of ZnCl 2 to produce 6-acyl-derivatives

苯并噻唑酮环的 6-位上进行酰化的方法,由
氯化锌而不是
氯化铝和 3-酰基-2(3H)-

生物催化的 Fries 样重排作为起始材料。该方法相对于其他酰化方法是有利的,因为它只需要三当量的 ZnCl 2 即可以 82-94% 的产率生产 6-酰基衍
