Stereoselective Synthesis of 2-[1-Methylpyridin-2(1Н)-ylidene]malononitrile Derivatives.

Abstract

An efficient synthesis of 2-[1-methylpyridin-2(1//)-ylidene]malononitrile derivatives have been identified, the reactions have been proved to be stereoselective; the spatial location of substituents has been determined.
