New entry to 9-acetyl/formyl-substituted 2H,8H-pyrano[2,3-f]chromen-2-ones through Baylis-Hillman reaction

A new facile route to 9-acetyl/formyl-substituted 2H,8H-pyrano[2,3-f] chromen-2-ones is described. The Baylis-Hillman reaction involving the condensation of methyl vinyl ketone/acrolein with 7-hydroxy-2-oxo-2H-chromen-8- carbaldehydes in the presence of diazabicyclo[2.2.2]octane (DABCO) under N2 atmosphere at room temperature furnished the desired compounds in good yields.
