Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The acylation of homoveratric acid and its derivatives with carboxylic acids in the presence of polyphosphoric acid, which leads to the synthesis of 2-acylhomoveratric acids, was studied. The properties and transformations of the latter to 2-benzo-pyrylium salts and isoquinoline bases were investigated. The structural analogs of the alkaloid papaverine were synthesized.
