[ 1 ] - Facile one-pot multicomponent synthesis of 2-amino-6-(2-oxo-2H-chromen- 3-yl)-4-arylpyridine-3-carbonitriles using Brønsted acidic ionic liquid as catalyst under solvent-free conditions
A series of 2-amino pyridine-3-carbinitrile derivatives incorporated coumarin moiety has developed via multicomponent condensation of 3-acetyl-2H-chromen-2-one, arylaldehydes, malononitrile and ammonium acetate utilizing Brønsted acidic ionic liquid, (4-sulfobutyl)tris(4-sulfophenyl)phosphonium hydrogen sulfate as catalyst under solvent-free conditions. Good yields, short reaction times, straig...
