چکیده
|
The one-pot multicomponent efficient and easily operational protocol has been developed for the synthesis of tetrahydropyrano[2,3-c]pyrazole-5-carbonitrile derivatives. the methods work via the multicomponent reaction between 5-methyl-2-phenyl-2,4-dihydro-3h-pyrazol-3-one , aldehyde and malononitrile catalyzed by the silica-supported dodeca tungstophosphoric acid (dtp/sio2) catalyst. the protocol is practically green, milder reaction condition, higher yield, with short reaction times and recyclability of the catalyst.
