Abstract :
In this work, a variety of highly substituted quinolines were readily synthesized via Friedlander annulation using Br?nsted acid silica-based sulfonic acid as a modified catalyst under solvent-free conditions at room temperature. This efficient procedure has the advantages of giving the target compounds in high yields, short reaction times, simple workup procedure, reusability of the catalyst, and environmentally benign conditions.
