Abstract
An efficient synthesis of dihydrofurocoumarins and furocoumarins is ac hieved from 4-hydroxycoumarins and olefins in the presence of Ag2CO3/C elite in moderate yields. The new method has been applied to the synth esis of the natural cyclobrachycoumarin isolated from Brachyclados meg alanthus. (C) 1998 Elsevier Science Ltd. All rights reserved.
