Various alkenyl 2-acetylamino-2-deoxy-β-D-glucopyranosides have been
subjected to the Sharpless asymmetric dihydroxylation protocol to yield the
corresponding diols, albeit with somewhat disappointing stereoselectivity. An
alternative, more traditional approach has yielded the optically pure
epoxyalkyl 2-acetylamino-2-deoxy-β-D-glucopyranosides as putative
inhibitors of chitinases. As well, an epoxypropyl chito-bioside and -trioside
have been prepared, each as mixtures of two diastereoisomers.
