摘要:
C-alkylation of 4-pentyn-1-ol (1) with 1-bromo-5-(tetrahydropyranyloxy)pentane, subsequent cis-hydrogenation, and PDC oxidation gave the C10 aldehyde 5. Its Wittig-Horner olefination, base-catalyzed deconjugation to the corresponding (3Z) compound, and enzymatic macrolactonization furnished (3Z,6Z)-dodecanolide (1).
