Sadeh, Fatemeh Noori published the artcileThree-component coupling approach for the synthesis of 4H-pyrans and pyran-annulated heterocyclic scaffolds utilizing Ag/TiO2 nano-thin films as robust recoverable catalyst, Category: isoquinoline, the main research area is silver titanium oxide nano thin film catalyst preparation Knoevenagel; chromenecarbonitrile green preparation; dimedone aryl aldehyde malononitrile Knoevenagel cyclocondensation silver titanium catalyst; hydroxycoumarin aryl aldehyde malononitrile Knoevenagel cyclocondensation silver titanium catalyst; resorcinol aryl aldehyde malononitrile Knoevenagel cyclocondensation silver titanium catalyst; pyranopyrimidine green preparation; barbituric acid aldehyde malononitrile Knoevenagel cyclocondensation silver titanium catalyst.
As a segment of ongoing surveys and with the aim of expansion of environmentally benign processes, a series of biol. varied substituted 2-amino-3-cyano-4H-pyrans and pyran-annulated scaffolds I [R = Ph, 4-MeC6H4, 2,3-(MeO)2C6H3, etc.], II [R = Ph, 2-FC6H4, 2,4-Cl2C6H3, etc.], III [R = Ph, 4-MeC6H4, 2-thienyl, etc.] and IV [R = Ph, 4-FC6H4, 4-BrC6H4, etc., R1 = H, Me] have been synthesized by tandem Knoevenagel cyclocondensation of aldehydes, malononitrile, and C-H-activated acidic compounds in aqueous ethanol in the presence of Ag/TiO2 nano-thin films as an eco-friendly, recyclable, and robust catalyst at 60°C. The salient features of this protocol are mild reaction conditions, producing target compounds in high yields, short reaction times, high atom economy, eco-friendly catalyst, easy isolation of products, and no column chromatog. separation Also, it was observed that the catalyst is highly stable during the reaction and is reused several times without any observable loss in catalytic performance.
