✦ Synopsis


The catalytic Baeyer-Villiger rearrangement of flavanones is described by the use of the homogeneous methyltrioxorhenium (MTO)/H 2 O 2 system. In these experimental conditions 3,4-dihydro-4-phenyl-1,5-benzodioxepin-2-ones and previously not reported para-quinone derivatives have been obtained in mild experimental conditions from acceptable to good yields.
