A new and expedient assembly of an interesting class of amido-substituted furo[4,5-c]coumarins has been successfully achieved through a one-pot sequential coupling and cyclization strategy starting from 4-hydroxycoumarin, aryl glyoxals and benzamide. All the reactions showed selectivity towards furo[4,5-c]coumarin, instead of the corresponding isoxazolo-substituted coumarins.
