The reaction between the arylaldehydes 1a,b and hexamethylphosphorous triamide 2 leads to the [aryl(dimethylamino)methyl]phosphonic bis(dimethylamides) 3a,b. These can be easily deprotonated by butyllithium in 1,2-dimethoxyethane and condensed with arylaldehydes to afford enamines 4a-f or deoxybenzoins 5a-f in fair to good yield.
芳基醛1a,b与六甲基磷酸三胺2之间的反应生成[芳基(dimethylamino)甲基]磷酸双(dimethylamide) 3a,b。这些产物可以通过在1,2-二甲氧基乙烯中用丁锂轻松去质子化,并与芳基醛缩合,得到烯胺4a-f或去氧苯醇5a-f,产率在中等到良好之间。
