CuSO 4 – d -glucose, an inexpensive and eco-efficient catalytic system: direct access to diverse quinolines through modified Friedländer approach involving S N Ar/reduction/annulation cascade in one pot

A one-pot, efficient approach to quinoline synthesis, directly from 2-bromoaromatic aldehydes/ketones in a H 2 O–EtOH mixture involving a sequence of S N Ar/reduction/annulation cascade using CuSO 4 - d -glucose, is devised.
