A variety of 1-substituted 2-diphenylphosphinoyl-3-hydroxy-1H-indoles 5a-d and 2-dimethoxyphosphoryl-3-hydroxy-1H-indoles 6a,c have been efficiently prepared by base-induced intramolecular cyclization of the appropriate Horner-Wittig and Wadsworth-Emmons reagents, 2-[(diphenylphosphinoyl)methylamino]-N,N-diethylbenzamides 3a-d and 2-[(dimethoxyphosphoryl)methylamino]-N,N-diethylbenzamides 4a,c, respectively.
通过适当的 Horner- 的碱诱导分子内环化,可以有效地制备各种 1-取代 2-二苯基膦酰基-3-羟基-1H-吲哚 5a-d 和 2-二甲氧基磷酰基-3-羟基-1H-吲哚 6a,c Wittig 和 Wadsworth-Emmons 试剂,分别为 2-[(二苯基膦酰基)甲基氨基]-N,N-二乙基苯甲酰胺 3a-d 和 2-[(二甲氧基磷酰基)甲基氨基]-N,N-二乙基苯甲酰胺 4a,c。
