The reaction of various 7-hydroxyflavones (1) with allyl bromide in potassium carbonate-acetone yielded the corresponding 7-allyloxy derivatives (2). Claisen rearrangement of 2 gives 7-hydroxy-8-allylflavones (3) which on reaction with equimolar quantity of mCPBA in dichloromethane furnish regioselectively 2,3-dihydro-2-hydroxymethyl-5-aryl-furo[2,3-h][1]benzopyran-7-ones (5) in good yields.
