Tertiary mercaptoketone, and fragrance and flavor composition containing the same

[PROBLEM TO BE SOLVED]: To provide a new fragrance and flavor element which have high acceptability, excel in odorant, flavor, depth, etc., and can be useful as a flavor seasoning substance for various products effectively, and to provide a fragrance and a flavor composition containing the same. [SOLUTION]: The tertiary mercaptoketone shown by following formula(I): [Wherein, R and R' are the same or different C1-C3 alkyl group; and the total carbon number of R and R' is 3 or 4], the method for producing the compound, and the fragrance and flavor composition containing the compound.

Acylations des cetones α-β-ethyleniques catalysees par les acides sulfoniques : synthese concomitante de sels de pyrylium et de dihydro-2,3-pyrones-4

The acylation of α,β-ethylenic ketones by carboxylic acid anhydrides catalyzed by sulfonic acids lead to the expected unsymmetrical pyrylium salts. 2,3-Dihydro-pyran-4-ones are also formed.The respective yields depend upon the alkyl substituents of the starting material.

PYRYLIUM SALTS FROM FRIEDEL-CRAFTS ACYLATION OF ISOPARAFFINS : ISOOCTANE

It is shown that acylation of isooctane in AlCl3/CHCl3 medium leads to 2,6-dialkyl-4-methylpyrynium salts, unsaturated ketones and isobutane.Compared to acylation of other isoparaffins, better yields are obtained due to an autocatalytic process.
