MICHAEL ADDITION OF<i>N</i>-(DIPHENYLMETHYLENE)- AMINOMETHYLPHOSPHONATE TO ACRYLATES USING PHASE TRANSFER CATALYSIS CONDITIONS: SYNTHESIS OF 1-(<i>N</i>-DIPHENYLMETHYLENE)AMINO- 3-(ALKOXYCARBONYL)- PROPYLPHOSPHONATES

Abstract

Phase transfer catalyzed Michael reaction of N-(diphenyl-methylene)-aminomethylphosphonate 1 to acrylates (2) provides a simple and convenient method for the synthe-sis of 1-(N-diphenylmethylene)amino-3-(alkoxycarbonyl)propylphosphonates (3).
