Preparation of resin bound [hydroxy(tosyloxy)iodo] benzene and its use in 5-benzoyldihydro-2 (3H)-furanone synthesis

摘要

A new type of polymer supported hypervalent iodine reagent, which is sufficiently reactive for the formation of 5-benzoyldihydro-2(3H)-furanone from 4-benzoylbutyric acid, has been prepared by a convenient method; the poly(4-iodostyrene), formed in the ractonization could be regenerated and recycled for reuse the same reaction.
