atmosphere to give 5-[(1′R,2′S,3′R-1′,2′,3′,4′-tetrabenzyloxy)butyl]tetrazole in a high yield via an unpreceding rearrangement with one carbon shortening of sugar skeleton. In contrast its photolysis afforded two tetrazoles caused by the rearrangements without one carbon degradation; 5-[(1′S,2′R,3′R,4′R-1′,2′,3′,4′,5′-pentabenzyloxy)-pentyl]tetrazole and 1-[1′R,2′S,3′R,4′R-1′,2′,3′,4′,5′-pentabenzyloxy)pentyl]tetrazole
1,1-Diazido-2,3,4,5,6-penta-O-benzyl-D-glucose 在邻二甲苯中氩气下回流得到 5-[(1'R,2'S,3' R-1',2',3',4'-四苄氧基)丁基]四唑通过糖骨架的一个碳缩短的前所未有的重排获得高产率。相比之下,它的光解提供了由重排引起的两个四唑,而没有一个碳降解;5-[(1'S,2'R,3'R,4'R-1',2',3',4',5'-五苄氧基)-戊基]四唑和1-[1'R,2 'S,3'R,4'R-1',2',3',4',5'-戊苄氧基)戊基]四唑。
