Abstract: A kind ofα.β-unsaturated derivative(2a—c)with isochro-
man—4 has been obtained by ALDOL condensation reaction, in
which the isochromanone reacts with aromatic aldehyde in presence of sodium hydroxide alcohol solution. And then a title compound(4a—c)with 83%-90% yield has been synthesized by the reaction of the(4a—c) and cyanoacetamide in ethanol solution containing sodium ethylateby Michel addition reaction.
The title compound synthesized is similar to method by dehydrogenation in existence of element Se with piperidine as catalyst. The chemical structure of the synthesized compounds (4a—c) has been proved by elemental analysis, IR and 1H NMR analysis.

Key words: heterocyclic compounds, synthesis, isochro-manopyridone
