Chemical synthesis of polysaccharides and polysaccharide mimetics
Ruiqing Xiao,Mark W. Grinstaff +1 more
TL;DR: In this paper, a review comprehensively describes the chemical polymerization methods to synthesize polysaccharides with different compositions and architectures (linear, branched, and hyperbranched) and the synthetic procedures to poly-saccharide mimetics possessing, for example, amine linkages, amide linkages and carbonate linkages.

Metal‐cation‐induced chiroptical switching for poly(phenylacetylene) bearing a macromolecular ionophore as a graft chain
TL;DR: In this paper, a poly(phenylacetylene) bearing a polycarbohydrate ionophore as a graft chain (copolymer 4) was synthesized by the copolymerization of end-functionalized (1→6)-2,5-anhydro-3,4-di-O-ethyl-D-glucitol with a 4-ethynylbenzoyl group (macromonomer 2).

Synthesis of hyperbranched carbohydrate polymers by ring-opening multibranching polymerization of anhydro sugar.
Toshifumi Satoh,Toyoji Kakuchi +1 more
TL;DR: The polymerization method, which proceeds through a ring-opening reaction by a proton-transfer reaction mechanism, is a facile method leading to a spherical carbohydrate polymer with a high degree of branching.

Rules for ring closure
TL;DR: The endocyclic closure of nucleophilic centres to polarized double bonds to give five-membered rings is impeded by restrictions of geometry; these restrictions can be overcome in acid through the generation of oxonium or protonated forms.

Chitin in nature and technology
TL;DR: Chitin has been a landmark for polysaccharides and modified chitins, besides chitin itself, to the point that three International Conferences on Chitin / Chitosan were convened (Boston, U.S. A. 1977, Sapporo, Japan 1982 and Senigallia, Italy 1985).
