A Lewis-acid-catalyzed selective reaction between anilines and glyoxylates was developed for synthesis of diarylmethanes or oxoimidazolidines. Under the catalysis of AgOTf, a series of anilines-based diarylmethanes, including primary, secondary, and tertiary anilines, were obtained in moderate to good yields. Moreover, stereoselective oxoimidazolidines were performed with the catalysis of Cu(OAc)2·H2O
开发了苯胺和乙醛酸盐之间的路易斯酸催化选择性反应,用于合成二芳基甲烷或氧代咪唑烷。在AgOTf的催化下,以中等至良好的收率获得了一系列基于苯胺的二芳基甲烷,包括伯苯胺、仲苯胺和叔苯胺。此外,在Cu(OAc) 2 ·H 2 O的催化下,进行了立体选择性氧代咪唑烷的制备。
