Synthesis and Liquid Chromatographic Determination of Optical Purity of NaphPropionate Liquid Crystals. — Various types of optically pure naphthyl propi13- 103 thyl
onate liquid crystals of type (III) are prepared as optically pure products by Mitsunobu
reaction. Improved yields are obtained from the reaction of naphthols, e.g. (II), with
4-(4-alkoxyphenyl)benzyl chlorides in the presence of K2CO3. However, completely
racemized products are obtained, which can be resolved by a commercial HPLC chiral
column, (S,S)-Whelk-O1. — (LEE, S. K.; SHIN, M. S.; LEE, J. G.; KANG*, K.-T.;
