Insect pheromone synthesis using Mn-salen catalyzed asymmetric epoxidation as a key step
摘要:
Enantioselective synthesis of three insect pheromones, (5Z, 13S)-5-tetradecen-13-olide, (9R)-decan-9-olide, and (S)-2-acetoxytridecane, has been achieved by using Mn-salen catalyzed asymmetric epoxidation as a key step.

prepared in good yields by coupling reaction of 1-alkynes or ω-functionalized 1-alkynes halides in the presence of a catalytic amount of (PPh3)4Pd and Cul. The reactions, which were carried out underphasetransferconditions employing benzyltriethylammonium chloride as phasetransfer agent, benzene as organic solvent and diluted aq NaOH as base, occurred with 100% stereospecificity when 1-halo-1-alkenes
