Abstract

The ability of 3-[α-(1,3-dioxo-2-indanyl)benzyl]-4-hydroxy-substituted 2H-benzo [b]pyran-2-ones and benzo[b]thiopyran-2-ones to undergo dehydration under the influence of dehydrating agents to give 7-aryl-6,7-dihydro-8H-indeno[1′,2′∶-2,3]pyrano[5,6-c]benzo[c]pyran-6,8-diones and their thio analogs was demonstrated.
