Oxazolidines From Sugars. III. A New Method for N-Alkyl and N,N-Dialkyl-D-Glucosamine Derivatives

Abstract Title compounds can be synthesised by an easy two-step method from the readily available benzyl 2-acylamino-4,6-O-benzylidene-2-deoxy-D-glucopyranosides (1–5), by nucleophilic cleavage of the oxazolidine ring previously formed between the positions 2 and 3 of the aminosugars.
