Aminoalkylation of Enhydrazinones

Enhydrazinones, prepared from dimedone and N,N-disubstituted hydrazines, react with formaldehyde and secondary amines to C-aminoalkyl-derivatives, pyrazolinium betaines and methylenebis(enhydrazinones).With better yields the C-Mannich products result from the reaction with methyleniminium salts.The enhydrazinones give with two moles of formaldehyde and primary amines the corresponding tetrahydropyrimidines. - Keywords: Mannich Reaction, Vinylogous Hydrazides, Tetrahydropyrimidines, Pyrazolinium Betaines, Methylenebis(enhydrazinones)
