Chemistry of Heterocyclic Compounds Aims and scope

Abstract

α-Methyl- and α,γ-dimethyl-substituted thieno-, thionaphtheno-, and thienothienopyridines, which are isosteres of quinaldine and benzoquinaldines, were synthesized by the condensation of the corresponding heterocyclic amines with paraldehyde via the Doebner-Miller reaction and with acetylacetone via the Combes method, respectively.
