    Abstract: PROBLEM TO BE SOLVED: To advantageously obtain the subject compound useful as a component of a liquid crystal composition by using a starting compound capable of being synthesized according to various methods. SOLUTION: (A) compound represented by the formula R -(A -Z )p -(A -Z )q -≡ [R is H, F atom, cyano, etc.; A to A are each independently a group represented by formula I, a group represented by formula II, etc.; Z and Z are each independently a single bond, C≡C, C=C, CH2 O, etc.; (p) and (q) are each 0 or 1] is reacted with (B) a compound represented by formula III [X to X are each CH, CF or N; Y and Y are each H or F atom and are not simultaneously H when (s) is 0; Y is H or F atom; (s) is 0 or 1; R is a 1-12C alkyl or a 1-12C alkoxyalkyl which may be substituted; E is a halogen, etc.] under basic conditions by using a metallic catalyst to afford a compound represented by formula IV. The components A and B are respectively obtained according to various methods and the component A is used in an equiv. amount of usually 0.9-10 times, preferably 1-2 times based on the component B.

    Abstract: PROBLEM TO BE SOLVED: To obtain an aromatic derivative useful for producing an intermediate for a medicine, an agrochemical, a liquid crystal, etc., especially an intermediate for a low-viscosity liquid crystal compound excellent in dielectric anisotropy. SOLUTION: This aromatic derivative is shown by formula I [R is a 1-12C alkyl, alkenyl or (substituted) benzyl; X is F; (r) is 0-3] such as 2-(4- benzyloxy-2,3-difluorophenyl)-5-(3-hydroxy-3,3,-dimethyl-1-propynyl)py rimidine. The derivative is obtained by reacting a phenylpyrimidine derivative of formula II (D is a halogen) with 1,1-dimethyl-2-propyne in the presence of a metal catalyst such as copper iodide to give an acetylene derivative of formula III and reacting the resultant substance with a basic substance such as triethylamine, etc.

    Abstract: PROBLEM TO BE SOLVED: To obtain in an industrially advantageous way the subject compound useful as an intermediate for medicines/agrochemicals. SOLUTION: The objective compound, an optically active N- benzyloxycarbonylpipecolic acid, is obtained by optical resolution of (±)-N- benzyloxycarbonylpipecolic acid with, as resolution agent, an optically active aralkylamine of the formula (A is an aryl; R is an alkyl or aralkyl) (e.g. optically active α-methyl-benzylamine) in a solvent such as methanol. It is preferable that the amounts of the respective reagents be as follows: 0.5-1mol of the optically active aralkylamine per mol of the (±)-N-benzyloxycarbonylpipecolic acid and 300-5000ml of the solvent per mol of the optically active aralkyl-amine.
