Using 2-azidobenzaldehyde and propargylamine in a Ugi–Smiles coupling gave easy access to 4,5-dihydro-1,2,3-triazolo[1,5-a][1,4]benzodiazepinederivatives. This novel approach is based on the reaction between 2-azidobenzaldehyde, propargylamine, isocyanides, and nitrophenols in methanol under reflux conditions without using additional reagents or catalysts.
在Ugi-Smiles偶联剂中使用2-氮杂苯并甲醛和炔丙胺可轻松获得4,5-二氢-1,2,3-三唑[1,5- a ] [1,4]苯并二氮杂卓衍生物。这种新颖的方法基于2-叠氮苯甲醛,炔丙基胺,异氰化物和硝基苯酚在甲醇中在回流条件下的反应,而无需使用其他试剂或催化剂。
