✦ Synopsis
Most important was the generality of the separability of diastereomeric @)-methyl lnctyl pyranosides (entries 1,5-9, Table 1) and furanosides (entries 10-12). Note that in entries 5,9,11, and 12, a second stereogenic center in the ring bearing a substituent is stereochemically "linked" t o the chirality at the anomeric center and can thus be resolved by this separation methodology.' However, diastereomeric ketofuranosides 13a and m "fro not chromatographically separable.
