Disclosed are novel 6-oxygenated-3,20-dioxo-pregnane derivatives of the general formula I
and specified 1,2-dihydroderivatives thereof. D is
,wherein Z represents specified acylgroups.
The other substituents of formula I include those commonly met in known corticosteroids.
The novel compounds may be prepared by methods known per se. The 6-acyloxy compounds of formula I are preferably prepared by subjecting a corresponding 6-oxo-compound of formula II, as herein defined, to esterification conditions. The 6-oxo-compounds of formula I are preferably prepared by oxidation of the corresponding 6-hydroxy-6,7-dihydro compounds. The novel compounds exhibit anti-inflammatory activity and are therefore useful in the treatment and control of inflammatory conditions.
