Abstract

A rapid and efficient method for the synthesis of alkyl 4-aryl-1,4,5,6,7,8-hexahydro-2,7,7-trimethyl-5-oxoquinoline-3-car boxylates by the condensation of 5,5-dimethylcyclohexane-1,3-dione and aromatic aldehydes with methyl 3-aminocrotonate or ethyl acetoacetate in the presence of ammonium acetate and of pyrimido[4
