- PRODUCTION METHOD OF CAPSINOID BY DEHYDRATING CONDENSATION, STABILIZING METHOD OF CAPSINOID, AND CAPSINOID COMPOSITION
-
In the production methods of capsinoid by esterification using an enzyme, a method of conveniently obtaining capsinoid in a high yield in a short time without using a dehydrating agent is provided. In addition, a method of stable preservation of produced capsinoid by purifying the obtained capsinoid under stable conditions is provided. A fatty acid represented by the formula (1) and a hydroxymethylphenol represented by the formula (2) are condensed without solvent or in a low-polar solvent, using an enzyme as a catalyst to give an ester compound represented by the formula (3). In addition, a fatty acid represented by the formula (4) is added to the ester compound represented by the formula (3) for stabilization. wherein each symbol is as defined in the specification.

- SYNTHESIS OF THE RACEMIC PROPIONATE OF 8-METHYL-2-DECANOL, THE SEX HORMONE OF THE SEVERAL LEAF-EATING BUGS Diabrotica (CHRYSOMELIDAE)
-
A new method has been developed for the synthesis of sex hormone of Diabrotica leaf-eating bugs, namely, the racemic propionate of 8-methyl-2-decanol, from 7-methyl-1-nonanol, which, in turn, was obtained by two methods using the Grignard reaction from furfural and from 2,3-dibromotetrahydropyran.
