Photo-induced Reactions: Part IV-Studies on Photo Fries Migration of Some Coumarins

Photo-Fries migration as an alternative route to acylcoumarins has been investigated. 7-Acetoxy- and 7-furoyloxy-coumarins give 6-acylcoumarins as the major products in contrast to Lewis acid mediated Fries migration where 8-acyl derivatives are the major products.The benzoates on the other hand give 6- and 8-acylcoumarins in equal proportions.The method is not suitable for the preparation of long chain unsaturated acyl derivatives of coumarins because in such cases photolytic deesterification is the main route.
