β-Acarbose. II. The Preparation of Various Carbohydrate Trifluoromethanesulfonates

Three carbohydrate trifluoromethanesulfonates, of potential use in the alkylation of a 1-epivalienamine derivative to produce precursors of ß-acarbose, have been prepared from the appropriate alcohols. The conversion of two of these trifluoromethanesulfonates into the primary amine, via the corresponding azide, is also reported.
