    摘要： Disclosed herein are a novel optically active naphthalene derivative, a process of the preparation thereof a ferroelectric liquid crystal composition containing the same and a liquid crystal element using the composition.
    The above optically active naphthalene derivatives including optically active naphthylcarboxylic acid derivative, hydroxynaphthalene derivative, alkoxynaphthylalkanol derivative and alkylnaphthylalkanol derivative have the following structural formula:
    wherein R' denotes an alkyl group of 3-20 carbon atoms, R 2 denotes an alkyl group of 1-20 carbon atoms optionally substituted with halogen atom(s) or an alkoxyalkyl group of 2-20 carbon atoms optionally substituted with halogen atom(s), X denotes -COO- or -OCO-, k, t and m denotes 0 or 1 respectively, n denotes an integer of 0-6, p denotes 0 or 1, and an asterisk indicates an asymmetric carbon atom, proviso when k is 0, t and m are not 1 at the same time, when k is 1, m is 1, and when n is 0 and m is 1, X is -COO-.
    These optically active naphthalene derivatives are useful as a ferroelectric liquid crystal material or its component having a sufficient spontaneous polarization and by which a high speed response is possible and which further exhibits a ferroelectric liquid crystal phase in a temperature region around room temperature.

    摘要： The invention provides novel compounds of the formula:
    and
    wherein m is 1 or 2, R 6 and R 7 , which can be the same or different are H or an alkyl group of 1 to 4 carbon atoms, or
    wherein n is 0 to 4, R 1 and R 2 , which can be the same or different are H, OH, alkoxy of 1 to 4 carbon atoms, benzyloxy or methoxymethoxy; R 3 is H, OH, halogen, alkoxy of 1 to 4 carbon atoms, benzyloxy, methoxymethoxy, 2,3-dihydroxypropoxy or
    can form an N-containing three-, four-, five- or six-membered heterocyclic ring; R 4 is OH, F, Cl, Br, I, mesyloxy, tosyloxy, formyloxy, alkylcarbonyloxy of 1 to 4 carbon atoms or CH 2 R 4 is replaced by CHO; R 5 is H or OH; or R 4 and R 5 together form an -0- bridge between the carbon atoms to which they are attached, and their non-toxic pharmaceutically acceptable salts and esters and mixtures thereof. Processes for the preparation of these compounds are described, and also novel pharmaceutical compositions containing them. These compounds exhibit valuable pharmacological properties as estrogenic, anti-estrogenic, and progestanic agents. They are also effective against oestrogen-dependent tumours. Certain compounds are useful as chemical intermediates for the preparation of pharmacologically active compounds of the invention.
