description	This specification relates to the production of 9.alpha.-halo-11.beta.-hydroxy-corticosteroids, to intermediates used in the production of such steroids, and to the production of such intermediates themselves. The specification is particularly concerned with the production of such steroids having anti-inflammatory action, e.g. beclomethasone dipropionate. There is disclosed a new route for preparing 9.alpha.halo-11.beta.-hydroxy-corticosteroids which involves the formation of novel 9.beta.,11.beta.-epoxy steroids which themselves may be conveniently obtained from the corresponding 9.alpha.-bromo-11.beta.-hydroxy-corticosteroids.
