β-Acarbose. III. The Attempted Alkylation of a 1-Epivalienamine Derivative with Various Carbohydrate Triflates

Abstract

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.
