The 5-hydroxy-lactar-6-en-13-oic-acid-γ-lactones (3, 11, 11a, 22a) were obtained by oxidation of their, naturally occurring, lactaro-furan derivatives (4, 13) using MCPBA or NBS.Reaction conditions, isolation of pure products and their characterization by spectral analyses are presented.

Oxidation of the furane ring of the so called furandiol (1) (known sesquiterpene isolated from the fungus Lactarius necator) showed a profound effect of neighboring hydroxyl groups on regioselectivity of this process.Protection of the secondary hydroxyl group by acetylation enabled us to synthesize only one isomer.Preparation of lactarorufin A from furandiol confirmed is stereochemical structure, as well as the hypothesis of formation of lactones from furans in biogenesis.
