6′-Hepta-O-pivaloylsucrose, readily available from sucrose, has been converted into 4-chloro-4-deoxy-galacto-sucroses, 4-amino-4-deoxy-galacto-sucrose, and 4-deoxysucrose, via nucleophilic displacement reactions. Similarly, 3,6,1′,3′,4′,6′-hexa-O-pivaloylsucrose and other readily available hexa-, penta-, and tri-pivalates have been converted into chloro and azido derivatives and also into various epoxides.
2,3,6,1',2',3',6'-庚糖-O-新戊酰蔗糖,很容易从蔗糖中获得,已经转化为4-氯-4-脱氧-半乳糖蔗糖,4-氨基-4 -脱氧半乳糖蔗糖和4-脱氧蔗糖,通过亲核取代反应。同样,3,6,1',3',4',6'-六-O-新戊酰基蔗糖和其他容易获得的六,五和三新戊酸酯已转化为氯代和叠氮基衍生物,以及各种环氧化物。
