aziridine intermediates, which underwent ring opening by reaction with various nucleophiles. The 5,6-diols resulting from selective hydrolysis of the terminal acetal group were subjected to (2-N→6-OH) cyclisation using two different methods for activation of 6-OH. Final deprotection of the N-nosyl and 3,4-acetal group proceeded smoothly to afford 6-substituted analogues of 1-deoxymannojirimycin.
将3,4; 5,6-二异亚丙基保护的1-氨基-1-脱氧-d-葡萄糖醇转化为N-甲苯磺酰基和N- nosyl活化的氮丙啶中间体,它们通过与各种亲核试剂反应而开环。使用两种不同的活化6-OH的方法,将末端缩醛基团选择性水解得到的5,6-二醇进行(2-N→6-OH)环化。N-烷基和3,4-缩醛基团的最终脱保护顺利进行,得到1-脱氧甘露糖霉素的6-取代类似物。
