Undermicrowave-assistedsolvent-freeconditions a one-pot reaction of triphenylphosphine, an aldehyde and N, N-diethyl chloroacetamide in the presence of zinc dust affords α, β-unsaturated amides stereoselectively in good yield. In comparison with the conventional heating method, the reaction was finished within five minutes under microwave irradiation.
在微波辅助的无溶剂条件下,三苯基膦、醛和 N, N-二乙基氯乙酰胺在锌粉存在下的一锅反应以良好的收率立体选择性地提供了 α, β-不饱和酰胺。与传统的加热方法相比,在微波照射下,反应在五分钟内完成。
