Chemistry of Heterocyclic Compounds Aims and scope

Abstract

The reaction of o-substituted aromatic amines with methacrylic acid gave N-aryl-α-methyl-Β-alanines, which were converted to dihydro-2,4-pyrimidinedione and dihydro-4-pyrimidinone-2-thione derivatives. The alkylation, acylation, and oximation of the dihydro-2,4-pyrimidinediones were accomplished. Conformational analysis of the compounds obtained was carried out by dynamic NMR methods.
