preponderance of regioisomeric sugar-derived tetrazoles (up to 75% total yield) obtained upon photolysis of protected (benzyl, acetyl) glucopyranosylidenediazides, even in the presence of added acrylonitrile, proved that azidonitrene intermediates predominate over anomeric carbenes, in the reaction. Revisions are presented for its mechanism and one structure.
Some sugar tetrazoles have been synthesized by the photolysis or the thermolysis of d-glucopyranosylidene diazide of d-galactopyranosylidene diazide. The reaction mechanism is discussed.
