METHOD FOR PRODUCING OXO-VINYL-IONOL AND O-PROTECTED DERIVATIVES THEREOF

The present invention relates to the preparation of oxovinylionol and its O-protected derivatives of the formula I (I) in which R is hydrogen or an OH protecting group, for example a group Si(Ra)3 by reacting a compound of the formula II (II) in which R have the meanings given above for formula I, i...

More Information
Summary:The present invention relates to the preparation of oxovinylionol and its O-protected derivatives of the formula I (I) in which R is hydrogen or an OH protecting group, for example a group Si(Ra)3 by reacting a compound of the formula II (II) in which R have the meanings given above for formula I, i.e. ?-vinyl ionol (formula II, R = hydrogen) or an O-protected derivative thereof (formula II, R = OH protecting group) with an oxidant in the presence of at least one transition metal, where the oxidant comprises at least one oxygen-containing compound which is selected from among hydrogen peroxide and organic hydroperoxides.
