Abstract
Abstract N-Peptidyl-d-glucosamines were synthesized by the stepwise reaction of N-carboxy α-amino acid anhydrides (4-alkyl-2,5-oxazolidinediones) with d-glucosamine hydrochloride in the presence of equimolar sodium methoxide in a mixture of acetonitrile and methanol, or in methanol, at a low temperature. Polymerization reaction of N-carboxy α-amino acid anhydrides (NCAs) did not occur at −50 °C. The mechanism of the reaction was then studied.
