Abstract
With cyanoacetic ester as raw materials,carbon disulfide and dimethyl sulfate,2-cyano-3,3-dimethy thioacrylate intermediates(1) was synthesized in ethanol as solvent under sodium ethoxide as catalyst reaction. Then 1reacted with β-phenyl ethyl amine to yield ethyl 2-cyano-3-methylthio-3-(β-phenylethylamine) acryl ate(2). Lastly,ethyl 2-cyano-3-methylthio-3-(β-phenylethylamine) acrylates(3) were obtained by the reaction of 2 with ethanolamine,n-Butylamine and cyclohexylamine. The structures of as-synthesized compounds were confirmed by elemental analysis,IR,1H NMR and13 C NMR.
