Abstract
A variety of salicylaldehydes effected tandem nucleophilic addition onto ketene, leading to corresponding coumarins in good yields under mild conditions. This "pseudocycloaddition" represents a very mild variant of the historic Perkin synthesis of coumarin (which remains of key interest in both perfumery and several emerging areas).
