On July 15, 2020, Uto, Takuya; Nakamura, Shota; Yamamoto, Kazuya; Kadokawa, Jun-ichi published an article.Application In Synthesis of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate The title of the article was Evaluation of artificial crystalline structure from amylose analog polysaccharide without hydroxy groups at C-2 position. And the article contained the following:

In this study, we found that a new artificial crystalline structure was fabricated from an amylose analog polysaccharide without hydroxy groups at the C-2 position, i.e., 2-deoxyamylose. The polysaccharide with a well-defined structure was synthesized by facile thermostable α-glucan phosphorylase-catalyzed enzymic polymerization Powder X-ray diffraction (XRD) anal. of the product indicated the formation of a specific crystalline structure that was completely different from the well-known double helix of the natural polysaccharide, amylose. Mol. dynamics simulations showed that the isolated chains of 2-deoxyamylose spontaneously assembled to a novel double helix based on building blocks with controlled hydrophobicity arising from pyranose ring stacking. The simulation results corresponded with the XRD patterns. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Application In Synthesis of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate

On August 7, 2019, Bhaumik, Atanu; Peterson, Gregory I.; Kang, Cheol; Choi, Tae-Lim published an article.Computed Properties of 2873-29-2 The title of the article was Controlled Living Cascade Polymerization To Make Fully Degradable Sugar-Based Polymers from D-Glucose and D-Galactose. And the article contained the following:

Monomers derived from glucose and galactose, which contain an endocyclic alkene (in the sugar ring) and a terminal alkyne, underwent a cascade polymerization to prepare new polymers with the ring-opened sugar incorporated into the polymer backbone. Polymerizations were well-controlled, as demonstrated by a linear increase in mol. weight with monomer-to-initiator ratio and generally narrow mol. weight dispersity values. The living nature of the polymerization was supported by the preparation of a block copolymer from two different sugar-based monomers. The resulting polymers were also fully degradable. They underwent fast and complete depolymerization to small mols. under acidic conditions. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Computed Properties of 2873-29-2

Dowgiallo, Matthew G.; Miller, Brandon C.; Kassu, Mintesinot; Smith, Kenneth P.; Fetigan, Andrew D.; Guo, Jason J.; Kirby, James E.; Manetsch, Roman published an article in 2022, the title of the article was The convergent total synthesis and antibacterial profile of the natural product streptothricin F.Reference of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate And the article contains the following content:

A convergent, diversity-enabling total synthesis of the natural product streptothricin F has been achieved. Herein, authors describe the potent antimicrobial activity of streptothricin F and highlight the importance of a total synthesis that allows for the installation of practical divergent steps for medicinal chem. exploits. Key features of synthesis include a Burgess reagent-mediated 1,2-anti-diamine installation, diastereoselective azidation of a lactam enolate, and a mercury(II) chloride-mediated desulfurization-guanidination. The development of this chem. enables the synthesis and structure-activity studies of streptothricin F analogs.
