An economical, simple, and efficient direct aldol reaction via the double activation of both aldehydes and ketones by ammonia has been developed. An unprecedented tandem Mannich reaction was observed when hydroxybenzaldehydes, pyrrole-2-carboxyaldehyde, and indole-3-carboxyaldehyde were employed to afford 2,2-dimethyl-6-aryl-4-pyrilidinones in moderate to good yields.
已经开发了通过氨对醛和酮的双重活化而进行的经济,简单和有效的直接羟醛反应。当使用羟基苯甲醛,吡咯-2-羧基醛和吲哚-3-羧基醛以中等到良好的收率得到2,2-二甲基-6-芳基-4-吡咯烷酮时,观察到了前所未有的串联曼尼希反应。
