Reaktionsschritte
The object is achieved by a new approach to the manufacture of α-tocopheryl acetate (TCPA). According to this approach, 2,3,6-trimethylhydroquinone-1-acetate (TMHQA) is reacted with either phytol (PH), isophytol (IP) or an (iso)phytol derivative to produce TCPA or 3-phytyl-2,5,6-trimethylhydroquinone-1-acetate (PTMHQA), whereupon the latter is submitted to ring closure to obtain TCPA.
