Abstract: Steroid compounds having various oxygen substitution on the steroid nucleus are disclosed. A specific functionality present on many of the steroid compounds is oxygen substitution at both of positions 6 and 7. Thus, certain steroids have oxygen substitution at C6 and C7, and some have specific stereochemistries such as 6? and 7? oxygen substitution, and an alpha hydrogen at the 5 position in addition to having 6? and 7? oxygen substitution. Steroids having 3,4-epoxy functionality are also disclosed. In addition, steroids having C17 pyran and ?-lactone functionality, with oxygen substitution at C6 and C7, or at C15, of the steroid nucleus, are disclosed.

A specific functionality present on many of the steroid compounds is oxygen substitution at both of positions 6 and 7. Thus, certain steroids have oxygen substitution at C6 and C7, and some have specific stereochemistries such as 6&agr; and 7&bgr; oxygen substitution, and an alpha hydrogen at the 5 position in addition to having 6&agr; and 7&bgr; oxygen substitution. Steroids having 3,4-epoxy functionality are also disclosed. In addition, steroids having C17 pyran and &dgr;-lactone functionality, with oxygen substitution at C6 and C7, or at C15, of the steroid nucleus, are disclosed.

Abstract: The present invention relates to a method of using a perchloric acid catalyzed reaction to make acyl derivatives of norprogesterone compounds and, in particular, 16-methylene-17.alpha.-hydroxy-19-norpregn-4-ene-3,20-dione.

Abstract: The solvate 3.beta.,5.alpha.,6.beta.-trihydroxy-6.alpha.,17.alpha.-dimethylpregnan-20- one monomethanolate, a crystalline intermediate in the manufacture of medrogestone, and a method for its production by displacing the solvent in a solution of 3.beta.,5.alpha.,6.beta.-trihydroxy-6.alpha.,17.alpha.-dimethylpregnan-20- one with methanol are disclosed.

Abstract: A process for the preparation of a compound of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of hydrogen, alkyl of 1 to 4 carbon atoms optionally substituted by halogen or a nitrogen or oxygen function and alkenyl and alkynyl of 2 to 4 carbon atoms, R.sub.2 is alkyl of 1 to 4 carbon atoms and the A, B, C and D rings are optionally substituted by at least one member of the group consisting of optionally protected --OH or .dbd.0, halogen, alkyl and alkoxy of 1 to 4 carbon atoms and alkenyl and alkynyl of 2 to 4 carbon atoms comprising reacting a compound of the formula ##STR2## wherein R.sub.1 and R.sub.2 and the A, B, C and D rings are defined as above with an oxidizing agent in the presence of water and an at least partially water-miscible solvent to obtain a compound of the formula ##STR3## wherein R.sub.1 and R.sub.

Abstract: A process for the preparation of novel 14.alpha., 17.alpha.-dihydroxy-17.beta.-substituted steroids by reacting 14.alpha.-hydroxy-17-oxo-steroids with metal organic compounds and the use of the said novel steroids in the production of 14.alpha., 17.alpha.-methylenedioxy-pregnane derivatives.

Abstract: 19-Fluoro- and cyano- substituted 21-hydroxyprogesterone derivatives and related compounds which are active as 19-hydroxylase inhibitors and useful as antihypertensive agents are described herein. The compounds are prepared using appropriate synthetic pathways which will vary according to the nature of the specific 19-substituted progesterone or related compound desired.
