HYDROGENATIONS OF TRIACETIC ACID LACTONE. A NEW SYNTHESIS OF THE CARPENTER BEE (Xylocopa hirsutissima) SEX PHEROMONE

Under a variety of catalytic conditions, triacetic acid lactone, I, has been hydrogenated to differently oxidized lactones (II, III and V).C-Methylation of one of them, (II) is the key step for a convenient preparation of the carpenter bee sex pheromone.
