摘要

A novel and convenient procedure for the oxidative cyclization of diols to the corresponding lactones was achieved using trichloro- and tribromoisocyanuric acids. The methodology provided 5–11-membered lactones in 50–98% yield under simple and mild conditions. A reaction pathway is proposed by experimental evidence and DFT calculations at M062x/6-311G(d,p) level.
