D-mannitol and L-iditol bis-epoxides, easily obtained fromD-mannitol, are convenient substrates for the synthesis of polyhydroxylated piperidines and azepanes, via a nucleophilic opening of one epoxy function followed by a spontaneous intramolecular ring closure. Using this strategy 1-deoxynojirimycin and analogues were prepared.

A series of enantiomerically pure azasugars (2,5-dideoxy-2, 5-imino-D-mannitol, 1-deoxynojirimycin, 1-deoxymannojirimycin, and related compounds) was synthesized from D-mannitol via aminoheterocyclization of C2-symmetric bis-epoxides and subsequently followed by ring isomerization in few cases. These compounds have been evaluated as inhibitors of several glycosidases (alpha- and beta-D-glucosidases

C2-Symmetrical tetrahydroxyazepanes were synthesized as inhibitors for glycosidases. Tetrahydroxyazepane 1 is a non-specific inhibitor of various glycosidases, while compounds 2, 3 and 4 specifically inhibit beta-N-acetylglucosaminidase, beta-glucosidase, and alpha-fucosidase, respectively, with Ki in the micromolar range. Compound 1 is not an inhibitor of HIV/FIV proteases, but its 3,6-difluorobenzyl

a C2 symmetry axis, and N-acetylglucosamine to a 6-acetamidoiminocyclitol. Asymmetrization of the meso azasugar was carried out by chemical means, to yield a 3-methoxy-4,5,6-trihydroxyazepane. An attempted enzymatic synthesis of the methoxy derivatives of these azasugars was unsuccessful, leading, however, to both enantiomers of 1-deoxy-2-O-methylmannojirimycin. Some of these c...
