A Convenient One-Pot Synthesis of β -(Trifluoromethyl)allylaminophosphonic and Benzylaminophosphonic Acids
摘要:
The reductive condensation of aminoalkylphosphonic acids with beta-chloro- or beta-ethylthio-(beta-trifluoromethyl)acroleins leads to secondary (trifluoromethyl)allylaminophosphonic acids in moderate to good yields. The method appears to be useful for the preparation of benzylaminophosphonic acids.
