Chemistry of Heterocyclic Compounds Aims and scope

Abstract

It was established that acetals of lactams react with enamino diketones to give cyclic dienediamines. The dienediamines obtained in the reaction of N-methyl-2-pyrrolidone diethylacetal with 2-aminomethylenedimedone and 2-N,N-dimethyl-aminomethylenedimedone are converted to 3-(Β-methylamino)ethyl-6,6-dimethyl-5,6, 7,8-tetrahydro-5-coumarinone hydrochloride when they are heated in dilute hydrochloric acid.
