Enantiomeric O,O-dimenthyl α-iminotrifluoroethylphosphonates: Novel chiral building blocks in asymmetric synthesis of α-trifluoromethylated α-aminophosphonic acid derivatives
Autor: Petro P. Onys’ko, Oleg V. Stanko, Yuliya V. Rassukana
Publikováno v: Journal of Fluorine Chemistry. 219:123-128
Based on reaction of (+)- or (-)-dimenthyl phosphite with trifluoroacetonitrile the synthesis of optically active O,O-dimenthyl α-iminotrifluoroethylphosphonates was developed. The synthetic potential of these novel chiral synthons was demonstrated
