D-甘露糖为原料,分别利用苄胺双取代和aza-Wittig反应,再经氧化和亲核取代反应,合成了带保护基的含叠氮基及醛基的五元及六元氮杂糖中间体,对相关反应条件、基团保护及反应机理等进行了探讨,并提供了一种选择性脱除三苯甲基保护基的方法.

关键词: 氮杂糖, 苄胺双取代, aza-Wittig 反应, 三苯甲基, 选择性去保护

Protected five and six membered azasugar intermediates containing aldehyde group or azide group were synthe-sized using D-mannose as starting material via benzyl amine disubstitution or aza-Wittig reaction, then the oxidation and SN2 substitution reactions, respectively. The studies on the reaction conditions, the protecting groups and the reaction mechanism were also carried out, providing a protocol to remove trityl (Tr) group selectively.

Key words: azasugar, benzylamine disubstitution, aza-Wittig reaction, trityl, selective deprotection
