Closed Access item Fragmentation of carbohydrate anomeric alkoxy radicals. A new general synthesis of cyclic ketoses

Authors:Armas, Pedro de
Francisco, Cosme G.
Suárez, Ernesto
Issue Date:5-Nov-1993
Publisher:Elsevier
Citation:Tetrahedron Letters 34(45): 7331-7334 (1993)
Abstract:Cyclic ketones can be specifically obtained when C2 hydroxymethylated carbohydrates undergo a tandem β-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.
Description:4 pages, 1 table, 1 scheme.
