Research Abstract

Ant ferroelectric liquid crystal compounds(AFCLs), which possess a chiral 1,1,1-trifluoromethyl-2-alkanol moiety, are known to be important high-speed switching devices. Kusumoto and his colleagues recently the synthesis of unique dimeric AFLCs molecules which contain optically active bis(trifluoromethyl)alkanediols as chiral core units. The reported means for preparing optically pure bis(trifluoromethyl)alkanediols, however, required a nuisance resolution process using HPLC on chiral phase. We previously reported that Candida antarctica lipase catalyzed trans-esterification of racemic 1,1,1-trifluoro-2-alkanols with perfect enantioselectivity. We also achieved the hydrolysis of acetate more effectively. We next attempted trans-sterification of diol 1 in organic solvent using vinyl acetate as an acyl donor. Trans-esterification, however, did not take place. Fortunately, hydrolysis reaction of (±)-1 proceeded smoothly to provide monoacetate and diol with efficient enantioselectivity. We report the results of lipase-catalyzed hydrolysis reaction of bis(trifluoromethyl)alkanediols. Using optically active bis(trifluormethyl)-alkanediols obtained in this reaction as starting materials, synthesis of novel dimer type AFCLs has been demonstrated.
