Use of the PMBOCH2 group (PMB: p-MeOC6H4CH2) as a substitute of CO2H provided high level of reproducibility and efficiency in construction of the full structure of 5,6-epoxyisoprostane A2. After the construction, the PMBOCH2 group was converted to CO2H by using (1) DDQ, (2) SO3·pyridine and (3) NaClO2 at pH 7. The acid, thus synthesized, was condensed with lyso-PC to furnish one of the title compounds
使用PMBOCH 2基团(PMB:p- MeOC 6 H 4 CH 2)替代CO 2 H在构建5,6-环氧异前列腺素A 2的完整结构中提供了高水平的再现性和效率。施工后,PMBOCH 2基团均转化成CO 2,通过使用(1)DDQ,(2)SO 3 H 3 ·吡啶和(3)的NaClO 2在pH 7的酸,由此合成,用冷凝溶血PC提供一种标题化合物。类似地,合成了14,15-区域异构体。
