A convenient one pot synthesis of substituted and unsubstituted 2, 4-diaryl-5-oxo-5,6,7,8-tetrahydro-2-chromens

Anhydrous zinc chloride catalysed reactions of arylideneacetophenones 2a-c give 2, 4-diaryl-5-oxo-5, 6, 7, 8-tetrahydro-2-chromens 4a-c with 1, 3- cyclohexanedione. Under similar conditions arylideneacetophenones 2a-b and 2d-f react with 5, 5 -dimethyl -1

SYNTHESIS AND CATALYTIC HYDROGENATION OF 5-OXOTETRAHYDRO-4H-CHROMENES

A systematic investigation was undertaken into the intramolecular heterocyclization of 2-(3-oxopropyl)-1,3-cyclohexanediones by the action of chemical reagents.It was established that the direction of the heterocyclization reactions depends on the structure of the initial compound, the temperature, and the cyclizing agent.It was shown that the investigated compounds can undergo cyclization with the formation of 5-oxo-5,6,7,8-tetrahydro-4H-chromenes, which are capable of being converted into hexahydrochromans and 5-oxo-1-oxabicyclodec-9-enes under the conditions of catalytic hydrogenation.
