摘要： In the method for producing an optically active chromancarboxylate of the present invention, one of the enantiomers of racemic chromancarboxylic acid is esterified in a solvent containing an alcohol in the presence of a biocatalyst. After the esterification, the other enantiomer, i.e., the non-reacted chromancarboxylic acid is separated out of the reaction mixture to obtain the aimed optically active ester. The optically active chromancarboxylate is useful as the material for medicines, agricultural chemicals, etc. The invention provides an efficient production method thereof which is industrially applicable.

摘要： The invention provides a process for producing a chroman compound represented by formula (1), characterized in that the process includes allowing a phenol, an unsaturated compound, and a formaldehyde to react in the absence of catalyst and in the presence of water in an amount by mole 1 to 10 times that of the phenol.According to the present invention, a high-purity chroman compound can be produced in the absence of catalyst and under mild conditions. In addition, the invention provides an industrial means for producing the compound, without using a large amount of an acid or a base serving as a reaction promoter or a catalyst, which would otherwise cause side reactions, apparatus corrosion, etc.

摘要： The present invention is a simple method, in which a specific amount of alkali is added to an enantiomeric mixture of an optically active organic carboxylic acid where enantiomers are present in a non-equimolar ratio, or in which the enantiomeric mixture of an optically active organic carboxylic acid is neutralized with an alkali, and then a specific amount of acid is added thereto, thereby separating an organic carboxylic acid salt in the mother liquor and a crystallized organic carboxylic acid from each other. The method makes it possible to obtain an optically active organic carboxylic acid with improved enantiomeric excess. The present invention provides a simple production method for obtaining an optically active organic carboxylic acid with improved enantiomeric excess from an enantiomeric mixture of an optically active organic carboxylic acid where enantiomers are present in a non-equimolar ratio.

摘要： 5-Tolyl-pent-2-ene is cyclized in liquid phase in the present of an aliphatic hydrocarbon to produce the corresponding dimethyltetralin. The use of the aliphatic hydrocarbon effectively prevents a side reaction such as dimerization of 5-tolyl-pent-2-ene to provide dimethyltetralin in a high yield. Also, 5-tolyl-pent-2-ene is cyclized in liquid phase or vapor phase in the presence of a catalyst comprising a carrier supporting sulfate ions to produce the corresponding dimethyltetralin. The catalyst supporting sulfate ions shows a high catalytic activity event at low temperatures. Therefore, the cyclization of 5-tolyl-pent-2-ene is conducted in a wide temperature range from low temperatures to high temperatures.
