Fused tetracyclic systems containing a quinoline nucleus represent an important class of
heterocyclic bioactive natural products and pharmaceuticals because of their significant and …

A metal/additive‐free, TBHP‐promoted synthesis of 12H‐Chromeno [2, 3‐b] quinolin‐12‐
ones from 2‐phenoloxyquinolinyl‐3‐carboxaldehydes has been described via cross …

A metal-free, TBHP-promoted economical route is developed via the sp2 C–H bond
functionalization strategy for the synthesis of indenoquinolinones, 4-azafluorenones and …

Pd mediated one pot sequential Sonogashira coupling followed by annulation using o-
alkynyl aldehyde is reported. Contrary to the established modes of ring closures, an unusual …

A convenient method for the facile synthesis of 1-trifluoromethyl-3-alkylidene-1, 3-
dihydrofuro [3, 4-b] quinolines was developed from the TBAB-catalyzed nucleophilic …

A simple one-pot two-step reaction comprising an Ugi four-component reaction (Ugi-4CR)
and copper-catalyzed intramolecular amide-aryl cyclization of heteroaryl chloride with amide …

Abstract An inexpensive 1 mol% FeCl 3· 6H 2 O reagent has been developed for the
synthesis of 1, 3-disubstituted 1H-pyrano [4, 3-b] quinolines from o …

A ligand-free Pd-catalyzed approach has been developed for the synthesis of dibenzo-fused
naphthyridines. The reaction involves a one-pot domino sequence of reactions involving C …

Base promoted and temperature dependent reactions of 3-(2, 2-dibromovinyl) quinolin-2
(1H)-ones have been described. At 50° C, the cyclization reactions afforded 2-bromofuro [2 …

TBHP-promoted domino synthesis of pyrano [4, 3-b] quinolin-1-ones is described from o-
