An efficient one-pot synthesis of dimethyl 1-(Aryl)-5-cyano-4-(cyclohexylamino)-1,2,5,6-tetrahydro-6-oxopyridine-2,3-dicarboxylate derivatives
Abstract: The reactive 1:1 intermediate produced in the reaction between cyclohexyl isocyanide and electron- deficient acetylenic esters or dimethyl acetylene dicarboxylate was trapped by 2-cyano-N-(Aryl) acetamides to provides highly functionalized oxopyridine (potential synthetic and pharmaceutical interest ) in acetonitrile under mild reaction conditions at ambient temperature after 24 h ...
متن کاملBenign synthesis of N-aryl-3,10-dihydroacridin-1(2H)-one derivatives via ZnO nanoparticle-catalyzed Knoevenagel condensation/intramolecular enamination reaction
An efficient construction of 2-(N-arylamino)benzaldehydes and N-aryl-3,10-dihydroacridin-1(2H)-one derivatives starting from 2- hydroxybenzaldehydes has been developed. The synthesis of N-aryl-3,10-dihydroacridin-1(2H)-ones is based on the Knoevenagel condensation of dimedone to various 2-(N-arylamino)benzaldehydes, followed by an intramolecular enamination in the presence of 20 mol% of nanocry...
