(1 S )-1,5-anhydro- d -(1, 2 H)glucitol and subjected to an addition reaction with methyl 4,6- O -benzylidene-2,3-dideoxy-β- d - erythro -hexopyranosid-[2,3- d ]-triazole, derived from the nitro alkene with lithium azide. The structure of the adducts was, by 1 H-n.m.r. spectroscopy, assigned the d - gluco configuration for the nitro sugar moiety.
摘要用(1S)-1,5-脱水-d-(1,2H)葡萄糖醇制备了C-1原子多为氘代的3-硝基己-2-烯吡喃糖苷,并与甲基4进行加成反应。由硝基烯烃与叠氮化锂衍生得到的6-O-亚苄基-2,3-二脱氧-β-d-赤型-己基吡喃糖苷-[2,3-d]-三唑。通过1 Hn.mr光谱法,将加合物的结构指定为硝基糖部分的d-葡萄糖构型。
