Polysubstituted anilines were prepared by the palladium-catalyzed cross-benzannulation of conjugated aminoenynes 1-4 with diynes 8. The reaction proceeded in a highly regioselective manner under mild conditions, and the anilines were obtained as single regioisomers. Our method complements the well-known precedures for the preparation of polysubstituted anilines which are widely used in organic synthesis
通过钯催化的共轭氨基炔1-4与二炔8的交叉苯甲酸酯化制备多取代的苯胺。反应在温和条件下以高度区域选择性的方式进行,并且苯胺以单一区域异构体的形式获得。我们的方法补充了众所周知的制备多取代苯胺的方法,这些方法广泛用于有机合成中。
