Hydroquinone derivatives useful in the production of vitamin E

The present invention is directed to novel hydroquinone derivatives which are useful as intermediates for the manufacture of (R,R,R)-α-tocopherol (natural vitamin E) as well as of racemic α-tocopherol. The invention is also directed to a process for the preparation of the hydroquinone derivatives of the invention.

Process for the manufacture of optically active compounds

There is described a novel process for producing hydroquinone derivatives of the formula STR1 wherein R is an ether protecting group, and their conversion into d-α-tocopherol, starting from compounds of the formula STR2 wherein R is an ether protecting group and R1 is hydrogen or an ether protecting group.
