摘要： NEW MATERIAL:A carboxylic acid expressed by formula I [R1 is 2-6C hydrocar bon; R2 to R4 are H, halogen, alkyl, alkoxy, carboxyl, carboxylate, -COOR5 (R5 is alkyl) or -R6SR7 (R6 is H or methylene; R7 is H or alkyl) and at least one or more of R2 to R4 are substituent groups other than H; ...... and -- is single or double bond] and derivatives thereof. EXAMPLE:2-[1-(7-Methoxynaphthyl)]caproic acid. USE:An enzyme inhibitor and herbicide, having the naphthalene ring and capable of powerfully inhibiting an enzyme cysteine synthetase(E.C.4.2.99.8) in a biosyn thetic system of L-cysteine. PREPARATION:For example, a compound expressed by formula II or III is reacted with a compound expressed by formula IV in the presence of zinc to provide a compound expressed by formula V, which is then passed through compounds expressed by formulas VI and VII to afford the objective compound expressed by formula I.

摘要： PURPOSE:To simply obtain the title compound of high purity with excellent color tone by liquid phase oxidation of the substituent(s) of an alkyl- and/or acyl-substituted naphthalene compound into a crude product which is then esterified, hydrolyzed and put to precipitation by addition of an acid. CONSTITUTION:Firstly, crude naphthalenecarboxylic acid(NCA) is produced by liquid phase oxidation using molecular oxygen of a naphthalene compound having substituent(s) selected from alkyl group, acyl group and oxidized intermediates therefrom in a solvent consisting of a lower aliphatic monocarboxylic acid in the presence of an oxidizing catalyst. The crode NCA is then esterified in the presence of an acid catalyst, and the resulting esterified product is washed with water, if desired, to remove water-soluble impurities, and hydrolyzed in water or its mixture with a water-miscible organic solvent in the presence of 1-5 equivalent, per ester group in the ester, of an alkali catalyst to remove insolubles by means of e.g. filtration. Thence, an appropriate acid is added to the resultant filtrate to precipitate NCA crystal, thus obtaining the objective NCA crystal >=99.5% in purity and >=0.05 in optical density.

摘要： PURPOSE:To obtain the titled substance useful as an intermediate for organic syntheses with a small amount of a solvent efficiently in high yield, by oxidizing 2,3-dimethylnaphthalene in a high concentration in a liquid phase with molecular oxygen in the presence of a specific catalyst containing essential elements such as cobalt, manganese, etc. CONSTITUTION:2,3-Dimethylnaphthalene as a raw material is oxidized with molecular oxygen in the presence of a catalyst containing cobalt, manganese, zirconium, and bromine as essential components in a solvent, preferably acetic acid preferably , to give the aimed compound. The concentration of the catalyst is preferably about 100-10,000ppm each essential element as the concentration in the solvent. An atomic ratio of bromine to cobalt is importantly kept
