A mild and efficient visible light–mediated one‐pot multicomponent tandem approach to construct 4‐oxo‐tetrahydroindoles in ethanol–water medium at room temperature has been described. The characteristics of reported methodology are the utilization of visible light, an ideal source of energy to generate CC and CN bonds from commercially available substrates namely dimedone, phenacyl bromides, and
已经描述了一种温和有效的可见光介导的单锅多组分串联方法,可在室温下在乙醇-水介质中构建4-氧代-四氢吲哚。所报告方法的特点是利用可见光,这是一种理想的能源,可以从可商购获得的底物,即二甲酮,苯甲酰溴和胺中生成C andC和CN键。所提出的方案与开发4-氧-四氢吲哚衍生物具有高度的兼容性,具有更高的选择性和高收率。此外,无金属合成,环境友好的溶剂,简便的后处理,高原子经济性,成本效益,反应时间短和广泛的底物范围是所报道方案的主要优点。
