Title: Process for preparing 7 -alkoxycarbonyl substituted steroids.
Inventor: LAWSON JON P
IPC: C07J21/00
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 -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 -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 -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 -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 -hydroxy-7 -methoxycarbonyl compound (hydroxyester), the 11 -hydroxy group is converted to a leaving group which is then abstracted to produce a -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.

Ground stations (220, 320, 620, 720, 820, 1120) and a satellite (210, 1110) transmit the same digital symbol stream over a same frequency spectrum. The symbol streams arrive in each service area of the ground stations (220, 320, 620, 720, 820. 1120) with a relative delay that is within a window for which a receiver is adapted to decode efficiently. Spectral efficiency is achieved by allowing the ground stations to share the same frequencies as the satellites.
