A single-mode microwave cavity synthesizer with temperature and pressure control was used to accelerate the Hantzsch synthesis of 4-aryl and 4-alkyl-2,6-dimethyl-1,4-dihydro-3,5-pyridinedicarboxylates. In comparison with both conventional methods and microwave-assisted reactions performed in a domestic microwave oven, shorter reaction times and higher yields were obtained. The improved yields under microwave conditions made it possible to synthesize a small library, with acceptable purity.
利用具有温度和压力控制功能的单模微波腔合成器加速了 4-芳基和 4-烷基-2,6-二甲基-1,4-二氢-3,5-
吡啶二
羧酸盐的汉兹合成。与传统方法和在家用微波炉中进行的微波辅助反应相比,反应时间更短,产率更高。在微波条件下,产率的提高使得合成具有可接受纯度的小型化合物库成为可能。
