1,2,3,4-Tetrahydro-β-carbolines have been synthesized in moderate to good yields in short reaction time using the ionic liquid [bbim] BF4 as reaction medium and promoter. There was no need for the use of an additional catalyst normally employed in Pictet-Spengler condensation.
使用
离子液体[bbim] BF 4作为反应介质和
促进剂,已在较短的反应时间内以中等至良好的产率合成了1,2,3,4-四氢-β-咔啉。无需使用通常在Pictet-Spengler缩合反应中使用的其他催化剂。
