Reactions of 2-(1-aryl-3-oxo-3-phenylpropylidene)-3,4-dihydronaphthalen-1(2H)-ones, 3-(1-aryl-3-oxo-3-phenylpropyl)-3,4-dihydro-2H-chromene-2,4-diones, and 3,3'-(arylmethylene)bis(3,4-dihydro-2H-chromene-2,4-diones) with hydrazine hydrate have been studied. Depending on the substrate structure, these reactions involve intramolecular heterocyclization with participation of the exocyclic double bond
