A series of new 2-, 3- and 4-benzylamino-2-, 3- and 4-deoxy derivatives of 1,6-anhydro-β-D-hexopyranoses were prepared from 1,6:2,3- and 1,6:3,4-dianhydro-β-D-hexopyranoses by treatment with benzylamine and converted into 2,3-(
A complete series of 2,3-dideoxy-2,3-epimino- and 3,4-dideoxy-3,4-epimino-1,6-anhydro-β-D-hexopyranoses were prepared by lithium aluminum hydride reduction of the corresponding
The treatment of a 1-epivalienamine derivative with 1,6:3,4-dianhydro-2-O-benzyl-β-D-galactose has given an amino alcohol capable of conversion into either a cyclic carbamate or an aziridine. All attempts at acetolysis of the 1,6-anhydro ring of the cyclic carbamate failed owing to the inherent reactivity of the (allylic) benzyl ethers present in the molecule. Therefore, following a reduction with lithium in ammonia and acetylation of the product, a new cyclic carbamate was obtained which underwent successful acetolysis to provide a heptaacetate. This heptaacetate could be transformed into the desired methyl β-D-glucoside and base hydrolysis provided the 6-hydroxylated derivative of a diastereoisomer of methyl acarviosin, a putative inhibitor of enzymes which process β-D-glucosidic linkages.
