We report a concise synthesis of the enantiomerically pure 1,2- TRANS-1,5- CIS-methyl esters of rosaprostol, a prostaglandin derivative used for the treatment of gastric and duodenal ulcers, -using as key step the chemo- and stereoselective Michael addition of a Grignard reagent to an unprotected hydroxycyclopentenone.
我们报告了罗沙前列醇的对映体纯 1,2- TRANS-1,5- CIS-甲基酯的简明合成,罗沙前列醇是一种用于治疗胃和十二指肠溃疡的前列腺素衍生物,使用化学和立体选择性迈克尔作为关键步骤将格氏试剂添加到未保护的羟基环戊烯酮中。
