Abstract
Abstract Vicinal α-hydroperoxy-tetrahydropyranyl ethers annelated to cyclododecane are smoothly converted by homolytic fission in about 75% yield to a mixture of the macrocyclic lactones 3, 4, and 5. Based on this observation, an economically feasible synthesis of Exaltolide 1 (> 65% yield) has been developed. The mechanism of this new β-fragmentation reaction is discussed.
