In(OTf)₃-catalysed A³-annulation strategy towards the synthesis of pyrazole-tethered quinoline derivatives and assessment of their luminescent properties

Abstract

In(OTf)3-catalysed approach has been devised for the synthesis of fluorescent pyrazole tethered quinoline derivatives via A3-coupling of 4-formyl-pyrazole-3-carboxylates, substituted aromatic amines and terminal alkynes. This strategy offers several advantages including...
