Hexamethylenetetramine (HMTA) catalyzes synthesis of new polyfunctionalized 4H‐pyrans by reaction of aromatic aldehyde, malononitrile, and β‐keto esters via one‐pot three‐component procedure in water medium. Addition of reactants was performed by two methods led to achieve similar results. Using HMTA in catalytic amount not only represents the economic face of the reaction, but also due to the use

Three series of new cyclic sulfones have been prepared by a one-pot multi-component reaction (MCR) starting from the readily available dihydro-2H-thiopyran-3(4H)-one-1,1-dioxide. The in silico screening of the synthesized compounds revealed their high anti-inflammatory, antiarthritic, antiasthmatic and antiallergic potential coupled with the strong probability levels of cystinyl aminopeptidase inhibition

A series of halogenated 2-amino-4-aryl-4H-pyrano[3,2-h]quinoline-3-carbonitrile derivatives were prepared via interaction of 8-hydroxyquinoline, 5-chloro-8-hydroxyquinoline, and 8-hydroxy-2-methylquinoline with various α-cyanocinnamonitriles. The assignments of the structure of all synthesized compounds were based on spectral data. The cytotoxic activities of the synthesized compounds against four

Newseries of hexahydroquinoline and fused quinoline derivatives were designed and synthesized. The thirty seven new compounds were screened for in vitro antitumor activity against HepG2, HCT-116 and MCF-7 cancer cells. Results indicated that compounds 2e, 2h, 5b, 5c, 6a, 7d and 9b have the strongest potency against the three cancer cells, and they were further screened for in vitro cytotoxicity against
