摘要：

Cyclic ketoses can be specifically obtained when C2 hydroxymethylated carbohydrates undergo a tandem beta-fragmentation-cyclization reaction promoted by the system iodosylbenzene-iodine, under mild conditions. Pentuloses and hexuloses in furanose and pyranose form are obtained via 1,5 and 1,6 intramolecular cyclization.
