A safe, practical and eco-friendly electrochemical methodology for the synthesis of 3-formylated indoles has been developed by the utilization of Me3N as a novel formylating reagent. Stoichiometric oxidants, metal catalysts, and activating agents were avoided in this method, and an aqueous biphasic system of n-Bu4NBF4/PEG-400/H2O was used as a recyclable and reusable reaction medium, which made this
                                    通过使用Me 3 N作为新型甲酰化试剂,开发了一种安全,实用且环保的电
化学方法,用于合成3-甲酰化的
吲哚。该方法避免了
化学计量的氧化剂,
金属催化剂和活化剂,并且将n -Bu 4 NBF 4 / P
EG-400 / H 2 O的
水相双相体系用作可循环和可重复使用的反应介质,从而实现了这种电合成方法更可持续和环保。该工艺扩大了N -EDG和N的底物范围和官能团耐受性-EWG
吲哚。此外,通过这种途径实现了药物和
