| description | A single step access to fused imidazopyridine involving [bmIm]OH promoted click cyclocondensation of N-methylisatin with 2-aminopyridine has been achieved. The title heterocyclic scaffolds were obtained in excellent yield with high purity. [bmIm]OH was found to be more attractive as it plays the role of solvent, base, and catalyst. |
