Patent CA-2579954-A1 (CA)
Inventor: DAVID PAUL
IPC: C07J53/00
Filed: 2005-08-25
Abstract: Processes are described for the conversion of a steroid substrate having a 4,7-carbonyl bridge to a structure comprising a 7.alpha.-alkoxycarbonyl substituent by reaction of the substrate with an alkoxy group source, preferably in the presence of a base. Several optional process modifications are described. The reaction may be conducted at a temperature greater than about 70~C, with substantially shorter residence times than are required at lower temperatures. A saponification target may be incorporated into the reaction medium to consume free hydroxide compounds. The product 7.alpha.-alkoxycarbonyl compound may be recovered by crystallization, residual steroid values may be recovered from the crystallization mother liquor by extraction, and the extract may be processed to produce a repulp solution wherein the steroids may be re-equilibrated to produce additional 7.alpha.-alkoxycarbonyl substituted steroid product. Alternatively, the repulp solution may be recycled to a primary reactor wherein 4,7-carbonyl bridge substrate is converted to 7.alpha.-alkoxycarbonyl product. The process is particularly useful in the preparation of eplerenone, wherein a diketone intermediate comprising a 4,7-carbonyl bridge is reacted with an alkali metal methoxide to yield an 11.alpha.-hydroxy-7.alpha.-methoxycarbonyl compound (hydroxyester), the 11.alpha.-hydroxy group is converted to a leaving group which is then abstracted to produce a .DELTA.-9,11 enester, and the enester is epoxidized to eplerenone. Also disclosed is an epoxidation reaction conducted at relatively low hydrogen peroxide to enester substrate ratio.
