The first intermolecular Michael addition of benzene leading to the formation of 3,3-diphenylpropionanilide is described. 2-Methoxyaniline was reacted with cinnamoyl chloride to give 2-methoxycinnamanilide (1) which was treated with aluminum chloride in benzene at 80°C to afford 2′-hydroxy-3,3-diphenylpropionanilide (4) in an 85% overall yield. Accordingly, 4′-hydroxy-2′-methyl-3,3-diphenylpropionanilide
描述了苯的第一次分子间迈克尔加成,导致形成3,3-二苯基丙酰苯胺。使2-甲氧基苯胺与肉桂酰氯反应,得到2-甲氧基肉桂酰苯胺(1),将其在80℃下用氯化铝的苯溶液处理,以85%的总收率得到2'-羟基-3,3-二苯基丙酰苯胺(4)。因此,由4-甲氧基-2-甲基肉桂酰胺(5)以76%的产率制备了4'-羟基-2'-甲基-3,3-二苯基丙酰苯胺(6)。
