摘要：

Aldopyranosuronic and aldofuranosuronic acid lactones, with one carbon less, can be specifically obtained when hexuronic and penturonic acids in pyranose or furanose forms undergo a tandem beta-fragmentation-cyclization reaction promoted by the system (diacetbxyiodo)benzene-iodine, under mild conditions. The lactones are formed via 1,5 and 1,6 intramolecular cyclization.
