Preparation of O-, S- and N-benzyl derivatives of 1,6-anhydro-β-D-hexopyranoses via aziridine ring opening

Article abstract of DOI:10.1135/cccc20021805

The aziridine ring opening of N-tosylepimino carbohydrates 1-6 having D-allo, D-manno, D-galacto and D-talo configurations with benzyl alcohol, benzylamine and phenylmethanethiol afforded 2-, 3- and 4-O-benzyl-, benzylsulfanyl and benzylamino derivatives of 1,6-anhydro-β-D-hexopyranoses of D-gluco, D-galacto and D-manno configurations 7-23 in 44-99% yields. Hexenopyranoses 24-26 were prepared from tosylepimino carbohydrates 1, 4 and 5 by intramolecular rearrangement of the aziridine ring.
