摘要

Intramolecular radical cyclisations involving α-acetal methyl centres, and 2 (5H)-furanone and maleate electrophores, allow the facile synthesis of spiro-and linear-fused γ-lactone ring systems eg (5),(6),(7) and (8) present in the 'ginkgolides' viz (1) and (2) produced by the ginkgo tree Ginkgo biloba.
