Ultrasound irradiaton accelerates hetero Diels-Alder reactions between 1-dimethylamino-1-azadienes and electron-defficient dienophiles.Besides the lower reaction times and increased yields, other advantages of the sonicated reactions are the possibility of isolating previously unknown adducts due to the milder reaction conditions and, in some cases, the decrease in side reactions.

The α,β-unsaturated hydrazone 3 reacts regioselectively with a wide range of dienophiles to give the corresponding adducts.Reductive cleavage of the N-N bond in the adducts gives tetrahydropyridines.

Cycloaddition reactions in the series of α,β-unsaturated dimethylhydrazones involving various dienophiles were studied.It was found that the successive cycloaddition of two molecules of electron-accepting olefins to the unsaturated dimethylhydrazones occurs.
