The transformation of arylcarboxaldehydes and/or - ketones 2 by three different routes into arylethylamines 3 and/or 4 is reported. According to the first route, the intermediate iminophosphonates 9 react through a classical PO-activated olefination. The second and the third involve the rearrangement of the iminophosphonates 9 into the vinylphosphoramidates 12.
我们报道了通过三条不同路线将芳基羧醛和/或酮 2 转化为芳基乙胺 3 和/或 4。根据第一条路线,中间体亚胺膦酸盐 9 通过经典的 PO 活化烯化反应。第二条和第三条路线涉及亚胺膦酸盐 9 重排为乙烯基膦酸酰胺 12。
