A rapid and highly convenient synthesis of nitriles from the corresponding aldoximes using 8-bromocaffeine (8-BC) is described. In this protocol, aldoximes react with 8-BC in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and N,N-dimethylformamide (DMF) to furnish the corresponding nitriles under both microwave-assisted and/or conventional heating (reflux) conditions in short times and in
描述了使用 8-溴咖啡因 (8-BC) 从相应的醛肟快速和高度方便地合成腈。在该协议中,醛肟在 1,8-二氮杂双环 [5.4.0] undec-7-ene (DBU) 和 N,N-二甲基甲酰胺 (DMF) 存在下与 8-BC 反应,在两种微波下提供相应的腈 -辅助和/或常规加热(回流)条件在短时间内和良好的产量。这种方法对于结构多样的醛肟非常有效,包括脂肪族、芳香族和杂芳香族肟。
