随着1,2,3-三唑衍生物在医药、农药、材料等领域的广泛应用, 其合成引起了广大化学工作者的关注. 但是对1,2,3-三唑衍生物N(1)位官能团的转换还很少有人研究. 通过碱和一价铜作为催化剂, 将N(1)位为磺酰基的1,2,3-三唑"一锅两步"转化为N(1)位为苄基、取代苄基、烷基或卤代烷基的1,2,3-三唑衍生物. 该方法具有反应条件温和、操作简单等特点. 同时, 我们根据捕捉到的反应中间体对反应机理进行了推测.

关键词: 1,2,3-三唑, 官能团转换, 烷基取代, 一锅两步

1,2,3-Trizaole derivatives have been widely used in the fields of medicine pesticide and materials. Thus, much attention has been paid to the synthesis of various 1,2,3-trizaole derivatives. However, the transformation of function group at N(1) position of 1,2,3-triazole derivatives was less studied. In this paper, in the presence of base and using copper salt as the catalyst, the sulfonyl group of 1,2,3-triazole derivatives could be transformed to other function groups in a "one-pot two-steps" manner, including benzyl, substituted benzyl, halide substituted alkyl or alkyl groups. This method exhibited mild reaction conditions and simple operation. Meanwhile, based on the captured reaction intermediate, the reaction mechanism was also proposed.
