A domino process involving Michael addition and carbocyclization has been developed starting from beta-N-allylamino enoates and various organometallic reagents (organozinc halides, diorganozinc reagents, and copper/zinc mixed species). In all cases the mechanism of this domino reaction has been evidenced to involve a radical-polar crossover mechanism.
从β-N-烯丙基氨基烯酸酯和各种有机金属试剂(卤化有机锌,二有机锌试剂和铜/锌混合物质)开始,开发了涉及迈克尔加成和碳环化的多米诺工艺。在所有情况下,都已证明该多米诺反应的机理涉及自由基-极性交叉机理。
