tandem reactions for the synthesis of α-naphthylamines and indeno[1,2-c]pyrrolones starting from (o-aklynyl)phenyl enaminones are described. When reactions were carried out in N,N-dimethylformamide (DMF) using a AgNO3 catalyst, α-naphthylamines were obtained in up to 89% isolated yields within 2 h. Whereas indeno[1,2-c]pyrrolones were produced in high isolated yields in the presence of benzoyl peroxide
描述了涉及化学选择性串联反应的合成方法,用于从(邻-炔基)苯基烯胺酮开始合成α-萘胺和茚并[1,2- c ]吡咯烷酮。当使用AgNO 3催化剂在N,N-二甲基甲酰胺(DMF)中进行反应时,在2小时内以高达89%的分离产率获得了α-萘胺。而在过氧化苯甲酰(BPO)和CuCl催化下,高分离产率生产茚并[1,2- c ]吡咯烷酮。
