    摘要: 2-Amino-2-deoxy-glycoses of the general structural formula: ##STR1## wherein R.sub.1 is hydrogen, alkyl (1-7C), substituted alkyl (1-7C), phenyl, substituted phenyl, benzyl, or substituted benzyl;R.sub.2 is alkyl, substituted alkyl, phenyl, or substituted phenyl;R.sub.3 is H or lower alkyl (1-10C) with the proviso that when the aminoglycose has the 2-amino-2-deoxy-D-glucose configuration, R.sub.3 cannot be H;R.sub.4 and R.sub.5 are same or different and are H, aliphatic or aromatic acyl (2-21C) or substituted acyl (2-21C);R.sub.6 is H, or R.sub.6 -R.sub.7 together is --CH.sub.2 --CH.sub.2 --CH.sub.2 --,R.sub.7 is H, alkyl (1-7C), hydroxymethyl, mercaptomethyl, benzyl, or substituted benzyl;R.sub.8 and R.sub.9 each is carboxyl, esterified carboxyl (1-7C), amidated carboxyl, or mono- or di-alkyl-(1-3C)-amidated carboxyl;provided that when R.sub.3 is lower alkyl, the stereochemistry at asymmetric center I can be either D or L, but that when the aminoglycose has the 2-amino-2-deoxy-D-glucose configuration, the stereochemistry at I cannot be D;when R.sub.7 is not H, the stereochemistry at asymmetric center II is either L or D; andthe stereochemistry at asymmetric center III is D.These compounds possess immunostimulatory properties.
