Synthesis of novel chromeno[4',3'-b]pyrano[6,5-b]quinoline derivatives

New coumarin heteroanalogs were synthesized by condensation of 2-amino-4-aryl-3-cyano-5-oxo-4 H ,5 H-pyrano-[3,2-c] chromenes and 1,3-cyclohexanedione in 35-78 % yield. 2011 · Copyright by Walter de Gruyter.

Zr@IL-Fe3O4MNPs as an efficient and green heterogeneous magnetic nanocatalyst for the one-pot three-component synthesis of highly substituted pyran derivatives under solvent-free conditions

The present study was conducted to synthesize Zr@IL-Fe3O4MNPs as a new magnetically recoverable heterogeneous catalyst, which was then characterized by Fourier transform infrared (FT-IR) spectroscopy, energy dispersive X-ray spectros

Efficient and facile synthesis of chromenopyrano[2,3-b] pyridine derivatives catalyzed by sodium carbonate

In this research, a number of new and known chromenopyrano[2,3-b]pyridine derivatives have been prepared. Initially, according to the reported procedure, pyrano[2,3-c]chromene derivatives were synthesized by the reaction between 4-hydroxycoumarin, aromati

Sodium ethylene diamine tetraacetate catalyzed synthesis of chromene derivatives via multi-component reactions at low catalyst loading

An efficient and practical protocol for the synthesis of chromenes derivatives catalyzed by a low-loading sodium ethylene diamine tetraacetate (2?mol%) as a catalyst via multicomponent reaction is reported. A wide range of aromatic aldehydes easily underg

Synthesis, screening and docking of fused pyrano[3,2-d]pyrimidine derivatives as xanthine oxidase inhibitor

In view of developing effective xanthine oxidase (XO) enzyme inhibitors, a series of 100 pyrano[3,2-d]pyrimidine derivatives was synthesized and evaluated for its in vitro XO enzyme inhibition. Structure activity relationship has also been established. Am

Visible light promoted synthesis of dihydropyrano[2,3-c] chromenes via a multicomponent-tandem strategy under solvent and catalyst free conditions

The development of unique, mild and efficient one pot, multicomponent-tandem synthesis of highly functionalized dihydropyrano[2,3-c]chromenes under photochemical activation is reported. The key feature of the present work is the utilization of visible lig

Highly efficient three-component, one-pot synthesis of dihydropyrano[3,2-c] chromene derivatives

An efficient and convenient method for synthesis of dihydropyrano[3,2-c] chromene derivatives by onepot, three-component reaction of aldehydes, malononitrile, and 4-hydroxycoumarin in the presence of a catalytic amount of hexamethylenetetramine is reporte
