“…For the synthetic reaction, cyclic b-(1,2)-a-(1,6) glucans (family III) showed catalytic activity in the multicomponent Strecker reaction, and self-acetylation was also reported [124,125]. Recently, the bio-sourced cyclic b-(1,2) glucans (family I) have been utilized efficiently for the synthesis of indolyl 4H-chromenes via one-pot three component reactions in water [126], and this type of novel eco-friendly supramolecular carbohydrate catalysts will be attractive in fine chemicals and industrial fields.…”

Cyclic b-glucans are unique constituents that are found in the periplasmic space and extracellular media of Agrobacterium, Rhizobium, Bradyrhizobium, Rhodobacter, Xanthomonas, and Ralstonia species. Based on their glycosidic linkages, they are classified into three groups composed of cyclic b-(1,2), b-(1,3)-b-(1,6), and b-(1,2)-a-(1,6) linked glucans. Their degrees of polymerization vary ranging from 10 to 40 glucose residues, and the backbone structure can be modified with non-sugar moieties. Since the macrocyclic oligosaccharides possess their own characteristics such as inherent three-dimensional structures, hydrogen bonding, and complex-forming abilities, various possible applications would be of interest in the field of green chemistry, separation science, pharmaceutical, and food industries. In this review, we have addressed the properties and current applications of bio-sourced cyclic bglucans and their derivatives.
