A simple and effective methodology for Claisen-Schmidtcondensation of (-)-menthone and other hindered cyclic ketones with aromaticaldehydes under highly basic conditions using a polar aprotic solvent and a strong base (alkali metal hydroxide or an alkoxide) is described and discussed.

Optically active benzylidene derivatives of camphor and menthone were obtained in preparative yields by condensation of the ketones with aromatic aldehydes in DMSO in the presence of t-BuOLi. The synthesized alpha, beta-unsaturated ketones show high specific rotation and thus are suitable to bedoping component to liquid-crystalline compositions.
