Title (EN) PROCESS FOR PREPARING ANGELIC ACID OR ITS ESTER
(FR) PROCEDE POUR LA PREPARATION DE L"ACIDE ANGELIQUE OU DE SON ESTER
Abstract:
(EN) A process for preparing angelic acid or its ester useful as perfume material, which comprises isomerizing tiglic acid using an organic sulfinic acid as a catalyst, and novel angelate esters represeented by formula (I), wherein R represents 3-hexenyl, 3-methyl-2-butenyl, 3-methyl-3-butenyl, 3-methyl-2-pentenyl, 3-methyl-4-pentenyl, CH3(CH2)$(1,3)$-(where $(1,3)$ is an integer of 5 to 9), cyclopentyl, cyclohexyl, 2-methylpentyl, alpha-methylbenzyl, neryl or furfuryl.
(FR) Procédé pour la préparation de l"acide angélique ou de son ester utilisables en tant que parfum qui comprend l"isomérisation de l"acide tiglique en employant un acide sulphinique organique comme catalyseur, et des esters angéliques nouveaux représentés par la formule (I), où R représente 3-hexényle, 3-méthyl-2 butényle, 3-méthyl-3-butényle, 3-méthyl-2-pentényle, 3-méthyl-4-pentényle, CH3(CH2)$(1,3)$ -(où $(1,3)$ est un entier entre 5 et 9), cyclopentyle, cyclohexyle, 2-méthylpentyle, alpha-méthylbenzyle, néryle ou furfuryle.
