iminophosphoranes (Staudinger reaction) and condensation with carbon disulfide to form nonisolated isothiocyanates; then, condensation with α-amino esters to provide new N-3-substituted 2-thiohydantoins. An efficient one-pot, two-step sequence starting from azide derivatives is described: first, formation of iminophosphoranes (Staudinger reaction) and condensation with carbon disulfide to form nonisolated
摘要 描述了一种从叠氮化物衍生物开始的有效的一锅,两步序列:首先,形成亚氨基正膦(Staudinger反应),然后与二硫化碳缩合形成非分离的异硫氰酸酯;然后,与α-氨基酯缩合,得到新的N-3-取代的2-硫代乙内酰脲。 描述了一种从叠氮化物衍生物开始的有效的一锅,两步序列:首先,形成亚氨基正膦(Staudinger反应),然后与二硫化碳缩合形成非分离的异硫氰酸酯;然后,与α-氨基酯缩合,得到新的N-3-取代的2-硫代乙内酰脲。
