Patent

CA 2190500

The instant invention involves a process for oxidizing compounds containing an allylic group, i.e. those containing an allylic hydrogen or allylic alcohol group, to the corresponding enones, using a ruthenium-based catalyst in the presence of a hydroperoxide. Particularly, .DELTA.-5-steriodal alkenes can be oxidized to the corresponding .DELTA.-5-7-keto alkenes.

L'invention concerne un procédé d'oxydation de composés contenant un groupe allylique, notamment ceux qui contiennent un groupe hydrogène allylique ou alcool allylique, en énones correspondants, au moyen d'un catalyseur à base de ruthénium et en présence d'un hydroperoxyde. On peut oxyder, en particulier, des .DELTA.-5-alcènes stéroïdiens en .DELTA.-5-7-cétoalcènes correspondants.
