Hydrazine Reactions, XIV. Reactions of Azido Sugars with HydrazineWith hydrazine 1,6-anhydro-2-azido-2-deoxy-D-glucopyranose (1), having an axial azido group, in an inhomogeneous reaction yields the 2-deoxy compound (2) and the glucal (3). Under similar conditions with glucoside 7, having an equatorial azido group, the deoxy compound 9 is obtained. The same reaction is suitable for the preparation of 1,5-anhydropentitols 18 and 19 from pentopyranosyl azides 15 and 16.
Notes:
1,6-Anhydro-2-azido-2-desoxy-D-glucopyranose-Derivate (1) mit axialer Azidogruppe reagieren mit Hydrazin uneinheitlich zu 2-Desoxy-Verbindungen (2) und Glucalen (3). Das Glucosid 7 mit äquatorialer Azidogruppe ergibt mit Hydrazin die Desoxy-Verbindung 9. Zur Gewinnung von 1,5-Anhydropentiten 18,19 aus Pentopyranosylaziden 15, 16 ist die Reaktion mit Hydrazin geeignet.
