Abstract:
The present invention relates to a process for the production of chromanol derivatives, more specifically to a process for preparing a compound of the general formula I wherein R1, R2 and R3 independently of each other are selected from hydrogen and methyl, R4 is selected from C-1-C6-alkyl, and X is selected from C1-C20-alkyl and C2-C20-alkenyl.
