SnO nanoparticles have been used as an efficient catalyst for the preparation of chromeno[2,3-b]pyridines and 2-amino-3,5-dicyano-6-sulfanyl pyridines under reflux conditions in ethanol in good to excellent yields. This flexible and nano-catalytic procedure showed good recyclability and provides a clean condensation reaction in a short reaction time. This journal is
Chitosan functionalized by citric acid: an efficient catalyst for one-pot synthesis of 2,4-diamino-5H-[1]benzopyrano[2,3-b]pyridine-3-carbonitriles 5-(arylthio) or 5-[(arylmethyl)thio] substituted
