Selective Tosylations of 3,6-Anhydrohexofuranosides with gluco, manno, and gulo Configuration

Selective monotosylation of methyl 3,6-anhydro-α-D-mannofuranoside (1a) preferentially yields the 5-O-tosylate 1e which opens via nucleophilic substitution access to β-L-gulo derivatives 2 by inversion of configuration at C-5.Analogously reaction of the d
