Diverse sets of 5,5'-disubstituted hydantoins can conveniently be made in moderate to good yields (40-92%) by a one-pot process involving treatment of aromatic, heteroaromatic or aliphatic nitriles with an organometallic reagent (RLi or RMgX) followed by KCN/(NH4)(2)CO3.
通过一锅法,包括用有机金属试剂(RLi 或 RMgX)处理芳香族、杂芳香族或脂肪族腈,然后以中等至良好的产率 (40-92%) 方便地制备不同组的 5,5'-二取代乙内酰脲通过 KCN/(NH4)(2)CO3。
