Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Reaction of 2-chlorocinchoninic acid anodes with malonodinitrile or cyanoacetic ester and potassium carbonate in refluxing DMF gives (4carbamylquinol-2-yl)malonodinitriles and -cyanoacetic esters respectively. Using UV and PMR spectroscopy it was shown that they exist in the ylidene form, being stabilized in the latter case by a chelate type intramolecular hydrogen bond.
