A one-pot synthesis of 2-amino-3-cyanopyridine derivatives has been demonstrated through the multicomponent reaction of aldehydes, ketones, malononitrile, and ammonium acetate using grapheneoxide as a heterogeneous catalyst in water as a green medium. The grapheneoxidecatalyst is very mild, effective, and most of its activity is preserved after being reused for five times.
