| titleOfInvention | Processes for preparation of 9,11-epoxy steroids and intermediates useful therein |
| abstract | Multiple novel reaction schemes, novel process steps and novel intermediates are provided for the synthesis of epoxymexrenone and other compounds of formula I, wherein: -A-A- represents the group -CHR4-CHR5- or -CR4=CR5-; R3, R4 and R5 are independently selected from the group consisting of hydrogen, halo, hydroxy, lower alkyl, lower alkoxy, hydroxyalkyl, alkoxyalkyl, hydroxycarbonyl, cyano, aryloxy, R1 represents an alpha-oriented lower alkoxycarbonyl or hydroxyalkyl radical, -B-B- represents the group -CHR6-CHR7- or an alpha- or beta-oriented group, where R6 and R7 are independently selected from the group consisting of hydrogen, halo, lower alkoxy, acyl, hydroxyalkyl, alkoxyalkyl, hydroxycarbonyl, alkyl, alkoxycarbonyl, acyloxyalkyl, cyano, aryloxy, and R8 and R9 are independently selected from the group consisting of hydrogen, halo, lower alkoxy, acyl, hydroxyalkyl, alkoxyalkyl, hydroxycarbonyl, alkyl, alkoxycarbonyl, acyloxyalkyl, cyano, aryloxy, or R8 and R9 together comprise a carbocyclic or heterocyclic ring structure, or R8 or R9 together with R6 or R7 comprise a carbocyclic or heterocyclic ring structure fused to the pentacyclic D ring, wherein the intermediates include compounds of formula D, E, F, 211, 210, 209, 208, 207, 206, 205, 204 and 203 as defined in claims 34 to 57. |
