Cycloadditions of hydroxylated enantiopure pyrroline N-with a racemic cis-dihydroxypyrroline N-oxide allowed the synthesis of two different pseudo imino-C-disaccharides oxides to 1,2-glycals display high double-asymmetric induction. The selectivity is controlled by the stereochemistry precursors in
