The rhodium-catalyzed regioselective amination of tertiary allylic trichloroacetimidates with unactivated aromatic amines is a direct and efficient approach to the preparation of α,α-disubstituted allylic aryl amines in good yield and with excellent regioselectivity. This method is applicable to a variety of unactivated primary and secondary amines and allows for the preparation of reverse prenylated
用未活化的芳族胺进行的铑催化的三烯丙基三氯乙酰亚氨酸叔胺的区域选择性胺化是制备α,α-二取代的烯丙基芳基胺的一种直接有效的方法,产率高,区域选择性好。该方法适用于各种未活化的伯胺和仲胺,并允许分两步制备反向的预酰化吲哚。
