Various carbohydrate triflates have been treated with cyclohexylamine and a 1-epivalienamine derivative to give some of the desired secondary amine, but mainly the product of a competing elimination reaction, namely a mixture of alkenes. When the reactions were conducted in the presence of potassium carbonate, novel carbohydrate carbamates were formed.
Three carbohydrate trifluoromethanesulfonates, of potential use in the alkylation of a 1-epivalienamine derivative to produce precursors of β-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.
