N-Alkyl and N-aryl-isoindolinones were prepared by a dioxane-mediated oxidation of isoindoline precursors. The transformation exhibits unique chemoselectivity for isoindonlines. A chiral tertiary (3°)-benzylic position was not racemized during oxidation, and methyl indoprofen was prepared by late stage oxidation. Mechanistic studies suggest a selective H atom transfer, which avoids many known oxidation (by-)products
N-烷基和N-芳基-异吲哚啉酮是通过二恶烷介导的异吲哚啉前体的氧化反应制备的。该转化表现出对异茚满碱独特的化学选择性。在氧化过程中手性叔(3°)-苄基位置未消旋,通过后期氧化制备了甲基吲哚洛芬。机理研究表明,选择性的H原子转移可避免许多已知的异吲哚啉酮氧化(副)产物。
