A selective method for 2-aryl-2H- and 4-aryl-4H-3,5-diformylpyrans synthesis from 1,1,3,3-tetramethoxypropane and aromatic aldehydes was developed using an FeCl 3 catalyst in MeOH― AcOH and an AlCl 3 catalyst in DMA―AcOH.
使用FeCl 3 催化剂在MeOH- AcOH和AlCl中,开发了一种由1,1,3,3-四甲氧基丙烷和芳香醛合成2-芳基-2H-和4-芳基-4H-3,5-二甲酰基吡喃的选择性方法3 催化剂在 DMA-AcOH 中。
