The development of switchable solvent-free multicomponent reactions to build high-value-added products is an important demand for organic synthesis. Herein, we detailed the successful implementation of a switchable strategy for the construction of diverse 4-fluoroalkyl-1,4-dihydropyrimidines and 4-fluoroalkyl-pyrimidines via a solvent/additive-free [3 + 2 + 1] annulation, starting from readily available
开发可切换的无溶剂多组分反应来构建高附加值产品是有机合成的重要需求。在此,我们详细介绍了通过无溶剂/添加剂的[3 + 2 + 1]环化成功实施了一种可切换策略,用于构建不同的4-氟烷基-1,4-二氢嘧啶和4-氟烷基-嘧啶,从容易开始可用烯胺、三氟乙醛水合物或1-乙氧基-2,2-二氟乙醇和脒盐酸盐。该反应符合绿色合成理念,为获取有价值的含氟杂环提供了新途径。
