    摘要: PURPOSE:To obtain a novel compound having high chemotherapeutic coefficient and high safety and useful as an antiviral agent by reacting a cyclopentene derivative with a 3-deazaadenine derivative in an inert solvent and eliminating protecting group from the reaction product. CONSTITUTION:A compound of formula I (Y is lower alkyl; R1' to R3' are OH-protecting group; X is electron-attracting eliminable group) is made to react with a compound of formula II (R4 is H or amino-protecting group) in an inert solvent (e.g. THF) in the presence of 2-5 equivalent of a base (e.g. sodium hydride) and 1-2 equivalent of a crown ether (based on the compound of formula I) e.g. at room temperature to obtain the objective compound of formula III (R1 to R3 are same as R1' to R3'), e.g. 6'-C-methyl-3-deazaneplanocin A derivative.

    摘要: PROBLEM TO BE SOLVED: To provide a new cyclohexane compound that can form a liquid-crystalline composition with improved response speed, by blending the compound with a nematic liquid crystal or the like.SOLUTION: The new cyclohexane compound represented by general formula (1) and a liquid-crystalline composition containing the compound are synthesized, thereby improving the response speed of the stable liquid-crystalline composition, (where in the formula: Rand Rrepresent the same or different R, ROCO or RCOO, R indicates an alkyl group, and the alkyl group may have an unsaturated bond; -CH-, -O-, -CO- or -COO- may substitute in the group; also part or all hydrogen atom(s) may be replaced with a halogen atom or a cyano group), X and Y each independently represent a halogen atom or a hydrogen atom, provided that both are not hydrogen atoms at the same time or/and X represents an oxygen atom and Y represents direct bond to the oxygen atom.
