摘要：
graphic Straightforward access to a new class Of D-gulo- and D-allo-derived directly linked (1-3)-imino-C-disaccharides by means of cycloaddition reactions of enantiopure polyhydroxylated pyrroline N-oxides with isolevoglucosenone is reported. The cycloaddition reactions display a high level of double asymmetric induction, which allows a partial kinetic resolution of a racemic nitrone.
