摘要
以吲哚、氧氯化磷和N,N-二甲基甲酰胺为原料,通过Vilsmeier-Haack反应合成吲哚-3-甲醛,产率为87.1%;再选择甲苯-水反应体系,用硼氢化钾作还原剂,在50~60℃下还原得吲哚-3-甲醇,反应条件温和,将反应、萃取、重结晶一次性完成,产率为69.0%。
In an industrial scale, indole-3-carboxaldehyde is obtained in a yield of 87.1% from indole by Vilsmeier-Haack reaction with phosphorus oxychloride and N, N-dimethylfomamide. Under the temperature between 50 - 60℃ indole-3- carboxaldehyde is reduced with potassium borohydride to give indole-3-carbinol in the presence of methylbenzene and water. The yield of indole-3-carbinol can reach 69.0%.
