Organocatalyzed epoxidation in the total synthesis of (-)-trans-, (+)-trans- and (+)-cis-disparlures

A simple, flexible and efficient organocatalyzed synthetic approach for the synthesis of (-)-trans-, (+)-trans- and (+)-cis-disparlures has been described. The pivotal reaction sequence comprises organocatalyzed asymmetric Jørgensen epoxidation, Wittig olefination, migration of epoxide and Mitsunobu inversion reaction. Excellent enantiomeric purity (≥99%) was achieved during the synthesis of disparlure enantiomers by the Jørgensen epoxidation key step.

Three decades of disparlure and analogue synthesis

Diverse syntheses of disparlure and its stereoisomers and analogues encompassing various strategies are compiled in this perspective.
