Phenyliodine(III) Triflate Mediated Synthesis of 5-Benzoyldihydro-2(3H)-furanones

摘要

A direct and efficient method for the preparation of 5-benzoyldihydro-2(3H)-furanones was realized by cyclization of 4-benzoylbutyric acids in the presence of phenyliodine(III) triflate.Lactonization methodology plays an important role in modern organic synthetic chemistry not only because lac-tones occur in nature in great abundance and variety,but also because they constitute a particularly useful class of syn-thons.
