Title (EN) NEW INTERMEDIATES FOR THE VITAMIN A AND β-CAROTENE SYNTHESIS
(FR) NOUVEAUX INTERMÉDIAIRES POUR LA SYNTHÈSE DE LA VITAMINE A ET DU Β-CAROTÈNE
Abstract:
(EN) The present invention relates to compounds of formula (I) wherein R1 signifies a C1-C15 alkyl moiety or a C2 to C18 alkenyl moiety, to their process of production as well as to their use in organic synthesis, especially as intermediates (building blocks) in the synthesis of vitamin A or β-carotene or derivatives thereof, or other carotenoids, e.g. canthaxanthin, astaxanthin or zeaxanthin, preferably vitamin A.
(FR) Cette invention concerne des composés de formule (I) - R1 dans la formule étant un fragment alkyle C1-C15 ou un fragment alcényle C2-C18, leur procédé de production ainsi que leur utilisation en synthèse organique, notamment en tant qu'intermédiaires (éléments structuraux) dans la synthèse de la vitamine A ou du β-carotène ou de dérivés de ceux-ci, ou d'autres caroténoïdes, par ex, canthaxanthine, astaxanthine ou zéaxanthine, de préférence de la vitamine A.
