| titleOfInvention | Processes for preparing 7-carboxy substituted steroids |
| abstract | This invention relates to processes for the preparation of 7-carboxy substituted steroid compounds of Formula (I) wherein R1 is selected from H or COR4; R4 is C1-C6 alkyl or C1-C6 alkoxy; R3 is C1-C6 alkyl; Z1 is -CH2- or Formula (II) wherein O-COR4 is in the α configuration; Z2 is -CH-; or Z1 and Z2 may be taken together to form a carbon-carbon double bond; Q is Formula (III). These intermediates are useful in the preparation of 7-carboxy substituted steroid compounds, and particularly, the invention is directed to novel and advantageous methods for the preparation of 9,11-α-epoxy-17-α-hydroxy-3-oxopregn-4-ene-α-7-21-dicarboxylic acid, Ϝ-lactone, methyl ester (eplerenone; epoxymexrenone). |
