SYNTHESIS AND THERMAL REARRANGEMENT OF OXYGEN HETEROCYCLIC SPIRANS [PDF]
Journal of Sciences, Islamic Republic of Iran, 1993 Thermal rearrangement of spirans (14) and (31) yields the xanthones (16,34) and diphenylrnethane (15, 32), respectively. The structure for xanthone (16), isolated from thermolysis, has been established by reduction to xanthene (20) followed by ...
