摘要:
A regio- and stereoselective iodination has been performed on vicinal diols located on ketopyranose templates using the controlled-Garegg conditions. 3-O-Benzy1-1,2-O-isopropylidene-beta-D-fructo- or psicopyranoses (1 or 4) were selectively iodinated, respectively, at C-5 or C-4 of the ketoses to afford the L-sorbo or D-sorbo iodohydrins.
