Abstract
NEW MATERIAL:A compound expressed by formula I (m is 4-10; * is asymmetric carbon). EXAMPLE:(S)-6-Hydroxynaphthalene-2-carboxylic acid-6'-methyl octyl ester. USE:A synthetic intermediate for optically active liquid crystal compound capable of providing extremely excellent ferroelectric liquid crystal, having wide temperature range and being photochemically and chemically stable. PREPARATION:2,6-Hydroxynaphthalene carboxylic acid expressed by formula II is benzylated and the benzylated product is converted into acid chloride derivative expressed by formula III using thionyl chloride, oxalic acid chloride, etc. then the above-mentioned acid chloride is reacted with various kind of optically active alcohols to give ester product expressed by formula IV, which is further subjected to debenzylation with hydrogen in the presence of pd/c to provide the compound expressed by formula I.
