A New Approach to the Synthesis of Peltogynoids, Natural Isochromenochromenes

The (+/-)-trimethyl ether of the unusual isochromenochromene 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 = OM

Synthesis of (+/-)-Trimethylpeltogynol via 6-endo Radical Cyclisation

The (+/-)-trimethyl ether of the unusual heterocycle peltogynol (3; R= OMe), and its ring skeleton (9; R= H), have been synthesised via 6-endo intracyclisation of the radical derived from the iodides (8; R= H) and (8; R= OMe).

Metabolites from the Purple Heartwood of Mimosoideae. Part 3. Acacia crombei C.T. White: Structure and Partial Synthesis of Crombenin, A Natural Spiropeltogynoid

Crombenin, 4,4',6,6',7-pentahydroxyisochroman-3'-spirobenzofuran-3(2H)-one, the first spiropeltogynoid, is related to the concominant crombeone (8-hydroxypeltogynone) from which it is derived via oxidation with alkaline hydrogen peroxide of the chalcone i
