K(2)CO(3)-Mediated Synthesis of Functionalised 4-Substituted-2-amino-3-cyano-4H-chromenes via Michael-Cyclization Reactions

An efficient approach for the synthesis of functionalized 4-substituted-2-amino-3-cyano-4H-chromenes moderate to high yields (up to 98%) has been achieved via a tandem K(2)CO(3 )catalyzed conjugate addition-cyclization reaction of malononitrile and a range of Knoevenagel adducts previously formed fr...
