Abstract
The protecting group free synthesis of Anomala Osakana Pheromone isomer has been achieved with high enantioselectivity (92% ee). A chiral γ-hydroxy-α, β-acetylenic ester was used as the key intermediate, which was obtained via asymmetric alkynylation of aldehyde. This was followed by readily handled selective hydrogenation and lactonization in three steps with a high overall yield (86%).
