SYNTHESIS OF CONJUGATED ω-DIMETHYLAMINOCARBONYL COMPOUNDS CONTAINING AN AZOMETHINE FRAGMENT

Krasnaya, Zh. A.,Bogdanov, V. S.

, p. 2057 - 2065 (1991)

Methods have been studied for synthesis of conjugated ω-dimethylaminocarbonyl compounds containing an azomethine fragment.The structures were established of all products from reaction of 2-aza-3-dimethylaminoacrolein acetal with CH-acids and of DMF acetal and β-dimethylaminoacrolein aminal with primary amines.It was shown that in many cases these reactions are accompanied by cleavage of the C=N, C-N and C=C bonds.
