title: Preparation of novel (1-->3)-beta-D-glucans having reducing glucose side chains.
abstract: Novel (1-->3)-beta-D-glucans (GPBCD, GPECD, GP6CD, and GP3CD) having reducing glucose side chains were prepared from a linear (1-->3)-beta-D-glucan (curdlan: CD) with halogeno glucose isopropylidene derivatives in dimethyl sulfoxide containing dimsyl sodium, followed by treatment with 40% trifluoroacetic acid to remove protecting isopropylidene groups. The side chain glucose moiety was linked or directly or through a spacer at various positions except for its anomeric carbon.
