Abstract: An environmentally friendly one-pot synthesis of Pyran and Benzopyran by using an activated C-H acid (4-hydroxy-coumarin), an aldehyde and malononitrile has been developed. The method uses ammonium acetate as a catalyst with water as solvent. The methods developed are simple and efficient in terms of time as well as yields.
