In this paper, a series of 3, 4-dihydro-isobenzopyran-fused heterocyclic compounds (2a-6b) were synthesized from 3, 4-dihydro-isobenzopyranone-4 and its β-diketon derivatives. Oxidation of these heterocyclic compounds by chromium trioxide furnished isocoumarin-fused heterocyclic compounds (7a-10b). The structures of all these compounds were characterized by elemental analysis, IR and 1HNMR spectra.
