• Chromone
• 3-halochromone
• DABCO
• furo[3,2-c]coumarin
• 1-benzopyran

A highly efficient synthesis of furo[3,2-c]coumarins have been achieved by a DABCO-catalysed reaction of 3-halochromones with 4-hydroxycoumarin. DABCO was found to be the most efficient catalyst among the different bases used for this reaction.
