The synthesis of β-D-glucoside tetraacetates of some higher alcohols, in order to use them as the starting materials in the study of transformation of β-glucosides into _??_-form, has been studied. Out of the procedures investigated, it seems to be convenient for
ttre
preparation of the β-glucosides to react acetobromoglucose with higher alcohols, in chloroform solution. In the presence of silver oxidF and absence of drierite.
The β-D-glucosides obtained in the present study are as follows: β-
n-butyl-D-glucoside tetraacetate, mp. 61° (uncorr.), [_??_]
21D-20.2° (chlfm.,
c 2.051), β-
n-heptyl-D-glucoside tetraacetate, mp. 62° (uncorr.), [_??_]
21D-20.3° (chlfm.,
c 1.576) and β-
sec-octyl-D-glucoside tetraacetat mp. 68° (uncorr.), [_??_]
23D-29.4° (chlfm.,
c 0.851).
