Oxidative 1, 2-aryl migration of alky aryl ketones (2, 5, and 8) to 2-arylalkanoates (3, 6, and 9) was effected by using diacetoxyphenyliodine (1). The migration was successfully applied to the preparation of the antiinflammatory agents ibuprofen (15) and clidanac (17).
通过使用二乙酰氧基苯基碘(1),实现了烷基芳基酮(2、5和8)的氧化性1,2-芳基迁移,转化为2-芳基烷酸酯(3、6和9)。这一迁移方法成功应用于抗炎药物布洛芬(15)和克利达那克(17)的制备。
