Abstract
Abstract
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.
