2-chloroalkylbenzothiazoles 1a-c react with alkoxides to give substitution and ring-expanded products 3 and 4. The substitution ring-enlargement competition much depends upon the solvent, the substitution reaction being preferred in alcohols and the ring-enlargement in DMF.
2-氯烷基苯并噻唑1a-c与醇盐反应生成取代基并进行环扩产物3和4。取代环的扩大竞争很大程度上取决于溶剂,在醇中优选取代反应,而在DMF中则优选环扩大。
