Unsymmetrical N-benzyloxycarbonyl-protected 1-amino-1-arylalkylphosphonate mixed diesters were synthesized using a one-pot reaction involving benzyl carbamate, aromatic aldehydes and alkoxydichlorophosphine, followed by treatment with alcohols in the presence of triethylamine. The reactions were followed by 31P NMR and a mechanism is proposed.
利用氨基甲酸苄酯、芳香醛和烷氧基二氯化膦的一锅反应,然后在三乙胺存在下用醇处理,合成了非对称的 N-苄氧羰基保护的 1-氨基-1-芳基烷基膦酸盐混合二酯。31P NMR 对反应进行了跟踪,并提出了一种机理。
