(DCE) to be used, and as a consequence, decomposition of less-reactive substrates could be avoided. High diastereoselectivity was observed in the synthesis of 2,5-disubstituted pyrrolidines. Ureas, bis(anilines), and alpha-amido pyrroles derived from 2-allylaniline could also participate in the diamination reaction.
通过使用有机可溶性新癸酸铜(II)[Cu(ND)2],可以改善羧酸铜(II)促进的氨化反应。Cu(ND)2允许使用极性较小的溶剂二氯乙烷(DCE),因此,可以避免反应性较差的底物的分解。在2,5-二取代的吡咯烷的合成中观察到高的非对映选择性。衍生自2-烯丙基苯胺的尿素,双(苯胺)和α-酰胺基吡咯也可能参与了金属化反应。
