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 α,β-unsaturated ketones show high specific rotation and thus are suitable to bedoping component to liquid-crystalline compositions.
