Diethyl Acetonedicarboxylate a Precursor for the Synthesis of New Substituted 4-Aminoquinolines and Fused 4-Aminopyridines

Article abstract of DOI:10.1007/BF00816102

The reaction of cyclic enaminonitriles 1 with diethyl acetonedicarboxylate (2) affords fused 4-amino-3-ethoxycarbonyl-2-ethoxycarbonylmethyl-pyridines 4.The course of the reaction and the yield of cyclic products were promoted by tin(IV)chloride.N-substit
