The preparation of both (2S)- and (2R)-1-monoricinolein derivatives has been developed to synthesize ferroelectric liquid crystals. Lipase-catalyzed hydrolysis of 2-protected-1,3-diricinoleins provided (2S)-1-monoricinolein derivatives with high diastereoselectivities, while transesterification of 2-protected glycerols with vinyl recinoleate gave (2R)-1-monoricinolein counterparts in good yields with high diastereoselectivities.
