摘要
以2-氰基芳醛和活泼亚甲基化合物(如丙二酸二甲酯、乙酰乙酸乙酯等)为原料,在无水碳酸钾催化下,通过无溶剂室温研磨反应,一步得到3-取代异吲哚啉-1-酮类化合物,产物无需柱层析。产物的结构通过核磁共振波谱和质谱解析确定。该反应具有操作步骤简单、反应时间短、适用范围广、产率高、高原子经济性等优点,是绿色有机合成反应,在新药设计与合成、天然产物合成中具有应用价值。
A solvent-free grinding reaction for the synthesis of 3-substituted isoindolin-1-ones from 2-cyanoarylaldehydes and various activated methylene compounds(such as dimethyl malonate and ethyl acetoacetate)has been developed.All the products were obtained without the tedious column chromatographic purification and were characterized using NMR spectroscopy and mass spectrometry.This method is advantageous because of its simple manipulation,short reaction time,wide substrate scope,high product yield,and high atom economy.It also has potential uses in novel-drug designing and natural product synthesis.
