Abstract
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.
