Polyhydroxylated pyrrolidines. Part 4: Synthesis from D-fructose of protected 2,5-dideoxy-2,5-imino-D-galactitol derivatives

The readily available 3-O-benzoyl-4-O-benzyl-1,2-O-isopropylidene-5-O- methanesulfonyl-β-d-fructopyranose (5) was straightforwardly transformed into its d-psico epimer (8), after O-debenzoylation followed by oxidation and reduction, which caused the inver
