| titleOfInvention | Δ9 (11) -5α-D-homo-20-keto steroids |
| abstract | 3α-Hydroxy and 3α-acyloxy- Δ 9 (11) -5α-D-homo-20-ketopregnenes of the formula ##STR1## wherein R is hydrogen or acyl, R 1 is hydrogen or methyl and R 2 is methyl or ethyl, are produced by esterifying a corresponding 3β-hydroxy-5α-20-keto pregnane of the formula ##STR2## wherein R 1 and R 2 have the values given above, with m-iodo-benzoic acid with inversion of the 3β-oxy group to a 3α-oxy group; chlorinating the thus-produced 3α-m-iodobenzoyl ester with dichloroiodobenzene under irradiation; and treating the reaction product with a dehydrohalogenating silver salt. Optionally thereafter, the 3α-iodobenzoyl group is split off in a conventional manner to produce the corresponding 3α-hydroxy steroid and optionally the thus-produced 3α-hydroxy steroid is esterified to produce a desired 3-ester thereof. |
