Herein, we report alkylative aromatization of tetralone for the synthesis of bioactive naphthols and benzo[e/g]indole derivatives using alcohols in the presence of NaOH via an aerobic oxidative cross-coupling protocol. This is a general and transition-metal-free method, which uses an inexpensive base, avoids inert conditions, and furnishes water and hydrogen peroxide as the byproducts. Moreover, this
在此,我们报告了四氢萘酮的烷基芳构化,用于在NaOH 存在下通过需氧氧化交叉偶联方案使用醇合成生物活性萘酚和苯并[ e / g ]吲哚衍生物。这是一种通用且不含过渡金属的方法,它使用廉价的碱,避免惰性条件,并提供水和过氧化氢作为副产品。此外,该方法具有广泛的底物范围,并获得了独有的区域选择性。
