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.

AN EFFICIENT SYNTHESIS OF (S)-CHROMANMETHANOL, A VITAMIN E PRECURSOR

The (S)-chromanmethanol, a key intermediate for the synthesis of optically active α-tocopherol was synthesized by a reaction sequence which utilized the asymmetric epoxidation of the (E)-allylic alcohol to the (2R,3R)-epoxyalcohol in high enantiomeric exc
