Selective Synthesis of Some Aminosugars via Catalytic Aminohydroxylation of Protected 2,3-Unsaturated D-Gluco- and D-Galacto-2-hexenopyranosides.

The aminohydroxylation of methyl 4,6-di-O-(tert-butyldimethylsilyl)-2,3-unsaturated -D-glucopyranoside proceeds in the presence of chloramine-T, OsO4 (4 mol%), (DHQ)2PHAL (5 mol%), and TEBAC in bo...
