The synthesis of some oligopeptides derived from novel carbohydrate α-amino acids

The attempted coupling of a carbohydrate α-azido acid with a carbohydrate α-amino ester in the presence of a diimide, hopefully to produce a dipeptide, yielded only the carboxylic anhydride. However, the combination of 4-toluenesulfonyl chloride in pyridi
