A novel one-pot rearrangement reaction, involving sequential epoxide rearrangement, condensation, cyclization and phenyl migration took place when 2,3-epoxydiphenyl ketones were treated with guanidine hydrochloride or urea in the presence of a base like sodium hydride and new type of imidazolone derivatives were obtained in good to excellent yields.
在氢化钠等碱和新型咪唑酮衍生物存在下,用盐酸胍或尿素处理 2,3-环氧二苯基酮时,发生了一种新的一锅重排反应,包括顺序环氧化物重排、缩合、环化和苯基迁移以良好到极好的收率获得。
