A new tricomponent reaction for the synthesis of symmetric and asymmetric alkyl bisphosphoramidates
2021
A novel three-component one-pot reaction procedure was designed for the synthesis of symmetric and asymmetric bisphosphoramidate derivatives. Our key reactants were a set of four aliphatic diamines, which individually react with two different phosphoryl chloride derivatives (N,N,N′,N′-tetramethylphosphorodiamide chloride and diphenyl phosphoryl chloride). A total of 10 products, six of them none reported before, were synthetized. The proposed experimental procedure does not involve any catalyst and proceeds under routine experimental conditions (room temperature and 1 atm). Each synthesized compound was characterized by NMR (1H, 13C, and 31P) spectroscopy and mass spectrometry. Graphical Abstract
