Page/Page column 22-24, (2017/06/24)
The subject of the invention is a novel process for the preparation of Carboprost tromethamine salt where alkylation the enone of the general formula (II) is carried out in the presence of a chiral auxiliary in aprotic solvent with a Grignard reagent. The methyl ester epimers of formula (VII) are separated by gravity silicagel chromatography and the salt formation is carried out by using solid tromethamine base.

This invention is a group of 8-beta, 12-alpha-PG2 (prostaglandin-type) analogs having variable chain length, or methyl or phenyl substitution in the hydroxy-substituted side-chain, and processes for making them. These compounds are useful for a variety of pharmacological purposes, including anti-ulcer, inhibition of platelet aggregation, increase of nasal patency, and labor inducement at term.
