Conventional,Microwave Induced and Photochemical Fries Rearrangement of Resorcinol Diacetate

摘要

The substituted resorcinol unit is a basic building block of a large number of naturally occurring valuable polyketide metabolite.However,syntheses of 2-substituted resorcinols were long and unproductive procedures.Acylation of resorcinol is known to occur at 4-position(ortho to one hydroxyl)rather than 2-position(ortho to both hydroxyls).
