An electrochemical synthesis method for the selective N1-acylation of indazoles has been developed. This “anion pool” approach electrochemically reduces indazole molecules generating indazole anions and H2. Acid anhydrides are then introduced to the solution resulting in selective acylation of the N1-position of the indazoles. This procedure can also be applied to the acylation of benzimidazoles and indoles
已经开发了用于吲唑的选择性N 1酰化的电化学合成方法。这种“阴离子池”方法通过电化学方式还原吲唑分子,从而生成吲唑阴离子和H 2。然后将酸酐引入溶液中,导致吲唑的N1位选择性酰化。该方法也可用于苯并咪唑和吲哚的酰化。也可以使用9 V电池进行反应,而不会损失反应效率。
