A highly efficient and useful method for the synthesis of bis[aryl(diethoxyphosphoryl)methyl]amines
has been developed. The treatment of aromatic aldehydes with ammonia followed by reaction
with diethyl phosphite in the presence of acetyl chloride as catalyst gives bis[aryl(diethoxyphosphoryl)methyl]amines.
This method is easy, rapid, and a high yielding method for the synthesis of bis[aryl(diethoxyphosphoryl)methyl]amines
with good diastereoselection from simple starting materials.
acetyl chloride - diethyl phosphite - aldehyde - bis[aryl(diethoxyphosphoryl)methyl]amine
- addition reaction
