PROCESS FOR SYNTHESIS OF 3-(N,N-DISUBSTITUTED-AMINO)-2- SUBSTITUTED ACRYLATE

摘要

Disclosed is a process for synthesis of 3-(N,N-disubstituted-amino)-2-substituted acrylate, which comprises carrying out amine-substitution reaction and elimination reaction for 2-substituted formylacetate alkali metal salt represented by formula (III) and amine complex represented by formula (II) in organic solvent 1 to obtain 3-(N,N-disubstituted-amino)-2-substituted acrylate represented by formula (I). The process uses N,N-disubstituted amine and carbon dioxide, or a liquid complex obtained by N,N-disubstituted amine and carbon dioxide as raw material, thereby it doesn't produce a side product influencing environment. The process has the advantages of reacting simply and operating easily.
