In(OTf)3-catalysed A3-annulation Strategy towards Synthesis of Pyrazole Tethered Quinoline Derivatives and Assessment of their Luminescent Properties

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...
