摘要：

New methodologies which lead selectively to chosen regioisomeric mono-O-acylsucroses are described. The results indicate that a selective ionization of the free sugar makes the secondary 2-OH group of the glucose moiety more nucleophilic than the primary hydroxyls. New 2-O-acylsucroses 2 and 2-O-(N-alkylcarbamoyl)sucroses 3 were thus obtained in high yields.
