A range of novel tetramethyl- and tetraethylisoindolinenitroxides, possessing aryl-linked carboxylic acids, amines, alcohols and phosphonic acids were prepared. Notably, the chemistry established for the aromatic dibromination of the tetramethylisoindolines was not easily transferred to the corresponding tetraethylisoindoline system. Instead, various tetraethylisoindoline analogues were accessed by
制备了一系列具有芳基连接的羧酸、胺、醇和膦酸的新型四甲基和四乙基异二氢吲哚硝基氧化物。值得注意的是,为四甲基异二氢吲哚的芳族二溴化建立的化学反应不容易转移到相应的四乙基异二氢吲哚系统中。相反,通过将连接到芳环上的甲基氧化得到羧酸来获得各种四乙基异二氢吲哚类似物。四乙基结构的空间体积增加应限制生物还原,这些化合物可能具有作为抗氧化剂的潜力。
