Low cost, non toxic nature, simple work-up and excellent yields of products are the main advantages of this work.}, keywords = {Pyridinium-1-sulfonic acid-2-carboxylic acid chloride,Hexahydroquinoline,multi-component condensation,β-Ketoester,Solvent-free}, url = {https://www.echemcom.com/article_97223.html}, eprint = {https://www.echemcom.com/article_97223_521231f92579d833d381ce982e0e448c.pdf} }
