The present invention relates to an improved process for the production of 4-alkanoyloxy-2-methylbutanoic acid, as well as to the use of such compounds in organic syntheses, especially in processes forming intermediates (building blocks) for the synthesis of organic compounds comprising isoprene (isoterpene) units, such as β-carotene or other carotenoids (e.g. canthaxanthin, zeaxanthin or astaxanthin) or as vitamin E or vitamin A as well as other structurally similar compounds.
本发明涉及一种改进的4-烷酰氧基-2-甲基丁酸的生产工艺,以及在有机合成中使用这种化合物,特别是在形成间接产物(构建块)的过程中,用于合成包含异戊二烯(异戊二烯)单元的有机化合物,例如β-胡萝卜素或其他类胡萝卜素(例如桔黄色素、玉米黄质或虾青素)或作为维生素E或维生素A以及其他结构类似的化合物。
