3-Alkyl-3-hydroxyoxindoles, a subclass of oxindole products, have antioxidant, neuroprotective, anticancer, and anti-HIV activities. In this study, a green and economical protocol for the synthesis of 3-alkyl-3-hydroxyoxindoles is developed for the first time via α-alkylation-α-hydroxylation of oxindole with benzyl alcohols without using any transition-metal catalysts in yields of 29–93%.
3-Alkyl-3-hydroxyoxindoles 是 oxindole 产品的一个子类,具有抗氧化、神经保护、抗癌和抗 HIV 活性。在这项研究中,首次开发了一种绿色和经济的合成 3-烷基-3-羟基吲哚的方案,该方案通过用苯甲醇对羟基吲哚进行 α-烷基化-α-羟基化,而不使用任何过渡金属催化剂,收率 29 –93%。
