Synthesis of Nitrogen Heterocycles from Methyl α‐ and β‐d‐Glucopyranosides
摘要:
Eight nitrogen heterocycles, mono and disubstituted tetrazoles and oxadiazoles, were synthesized from methyl D-glucopyranoside anomers. The monosubstituted tetrazoles resulted from the reaction of 6-cyanoglucopyranoside derivatives with sodium azide. By alkylation of the monosubstituted tetrazoles, the 1,5 and 2,5 disubstituted tetrazoles were obtained. The monosubstituted tetrazoles were reacted with acetic anhydride to give the oxadiazoles.
