摘要：

The (+/-)-trimethyl ether of the unusual isochromeno[4,3-b]chromene peltogynol 1 (R = OMe) and its ring skeleton 1 (R = H) have been synthesized via 6-endo intramolecular cyclisation of the radicals derived from the 3-(o-iodobenzyloxy)chromones 17 (R = OMe) and 17 (R = H) respectively. The spiroketone 13 can be prepared similarly from 2-(o-iodophenoxymethyl)chromone 12.
