An efficient oxidation–reduction condensation reaction of diazaphosphites with various nonacidic pronucleophiles in the presence of DIAD as a weak oxidant has been developed for carbon–heteroatom bond formation. This mild process affords structurally diverse tertiary amines, secondary amines, esters, ethers, and thioethers in moderate to excellent yields. The selective synthesis of secondary amines
在DIAD作为弱氧化剂存在下,已经将重氮亚磷酸酯与各种非酸性原核生物进行了有效的氧化还原缩合反应,以形成碳-杂原子键。这种温和的过程以中等到极好的收率提供了结构多样的叔胺,仲胺,酯,醚和硫醚。已经实现了从伯胺选择性合成仲胺。重要的是,已经证明了在合成抗帕金森病药物匹立贝地尔中的实际应用。
