Abstract A fast, general, environmentally friendly, and facile method for preparation of 5, 5-disubstituted hydantoins from the reaction between ketone (or aldehyde) derivatives with KCN and ammonium carbonate under microwave irradiation is presented. The microwaves remarkably accelerated this reaction, the reaction times decreased dramatically, the reaction conditions were milder, and the yields were
摘要 提出了一种快速、通用、环保、简便的方法,由酮(或醛)衍生物与 KCN 和碳酸铵在微波辐射下反应制备 5, 5-二取代乙内酰脲。微波显着加速了该反应,反应时间显着减少,反应条件温和,产率也更高。还进行了微波与经典条件的比较研究。所有产物均通过红外、核磁共振和CHN分析表征,其熔点与文献报道的已知化合物的熔点相同。这种方法可能在未来用于制备类似的衍生物。[本文提供补充材料。去出版商'
