2-Amino-2-deoxy-.beta.-D-glucopyranosyl-(1-4)-2-amino-2-deoxy-D-glucoses 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 alky, phenyl, or substituted phenyl and each R.sub.2 may be the same group or a different group; R.sub.3 is H or ##STR2## wherein R.sub.8 is H or lower alkyl (1-10C), and provided at least one of R.sub.3 is not H, R.sub.9 is H, or R.sub.9 -R.sub.10 together is --CH.sub.2 --CH.sub.2 --CH.sub.2 --; R.sub.10 is H, alkyl (L-7C), hydroxymethyl, mercaptomethyl, benzyl, or substituted benzyl; R.sub.11 and R.sub.12 each is carboxyl, esterified carboxyl (1-7C), amidated carboxyl, or mono- or di-alkyl- (1-3C) amidated carboxyl; R.sub.4 and R.sub.5 are the same or different and are H, aliphatic or aromatic acyl (2-21C) or substituted acyl (2-21C); when R.sub.8 is lower alkyl, the stereochemistry at asymmetric center I can be either D or L; when R.sub.10 is not H, the stereochemistry at asymmetric center II is L; the stereochemistry at asymmetric center III is D. These compounds possess immunostimulatory properties.
