Guo, Xiurong;Xin, Guang;He, Shiliang;Wang, Yanyan;Huang, Baozhan;Zhao, Hang;Xing, Zhihua;Chen, Qingming;Huang, Wen;He, Yang published 《Novel organic gelators based on pentose derivatized diosgenyl saponins》 in 2013. The article was appeared in 《Organic & Biomolecular Chemistry》. They have made some progress in their research.HPLC of Formula: 144490-03-9 The article mentions the following:

Much attention has been paid to diosgenin saponins because of their various bioactivities, whereas their gelation ability has never been reported. We synthesized some new saponins with pentose directly connected to diosgenin in a shorter procedure, which neither removed the acetyl group of the anomeric hydroxyl group selectively nor activated it and led to a higher yield, compared with the common synthesis of other diosgenyl saponins. We found these compounds are gelators of various organic solvents and their gel formation was studied with FTIR and SEM. This serendipitous discovery enriches the diversity of steroidal small mol. gelators. Meanwhile, single crystal X-ray anal. gave addnl. information about their intermol. interactions in the solid state. And (2R,3S,4S,5S)-5-(Acetoxymethyl)tetrahydrofuran-2,3,4-triyl triacetate (cas: 144490-03-9) was used in the research process.

Safety of (2R,3S,4S,5S)-5-(Acetoxymethyl)tetrahydrofuran-2,3,4-triyl triacetateIn 2017, Amdouni, Hella;Robert, Guillaume;Driowya, Mohsine;Furstoss, Nathan;Metier, Camille;Dubois, Alix;Dufies, Maeva;Zerhouni, Marwa;Orange, Francois;Lacas-Gervais, Sandra;Bougrin, Khalid;Martin, Anthony R.;Auberger, Patrick;Benhida, Rachid published 《In Vitro and in Vivo Evaluation of Fully Substituted (5-(3-Ethoxy-3-oxopropynyl)-4-(ethoxycarbonyl)-1,2,3-triazolyl-glycosides as Original Nucleoside Analogues to Circumvent Resistance in Myeloid Malignancies》. 《Journal of Medicinal Chemistry》published the findings. The article contains the following contents:

A series of nucleoside analogs, e.g. I, bearing a 1,4,5-tri-substituted-1,2,3-triazole aglycon was synthesized using a straightforward click/electrophilic addition or click/oxidative coupling tandem procedures. SAR anal., using cell culture assays, led to the discovery of a series of compounds belonging to the 5-alkynyl-1,2,3-triazole family that exhibits potent antileukemic effects on several hematol. malignancies including chronic myeloid leukemia (CML) and myelodysplastic syndromes (MDS) either sensitive or resistant to their resp. therapy. Compound I also proved efficient in vivo on mice xenografted with SKM1-R MDS cell line. Addnl., some insights in its mode of action revealed that this compound can induce cell death by caspase and autophagy induction. To complete the study, the researchers used (2R,3S,4S,5S)-5-(Acetoxymethyl)tetrahydrofuran-2,3,4-triyl triacetate (cas: 144490-03-9) .

COA of Formula: C13H18O9In 2011, Pan, Mei-Ying;Hang, Wen;Zhao, Xiao-Jun;Zhao, Hang;Deng, Peng-Chi;Xing, Zhi-Hua;Qing, Yong;He, Yang published 《Janus-type AT nucleosides: synthesis, solid and solution state structures》. 《Organic & Biomolecular Chemistry》published the findings. The article contains the following contents:

Novel Janus-type nucleoside analogs (1a-d) were synthesized. Their pyrimido[4,5-d]pyrimidine base moiety has one face with a bidentate Watson-Crick donor-acceptor (DA) H-bond array of adenine and the other face with an acceptor-donor (AD) H-bond array of thymine. These nucleosides may self-associate through the self-complementary base pair. Indeed, in the solid state, compound 6d displayed a honeycomb-like supramol. structure with tetrameric membered cavities formed through the combination of reverse Watson-Crick base pairs and aromatic stacking, in which the solvent mols. were accommodated. The result of temperature-dependent CD studies showed that the free nucleosides can form higher order chiral structures in aqueous solution And (2R,3S,4S,5S)-5-(Acetoxymethyl)tetrahydrofuran-2,3,4-triyl triacetate (cas: 144490-03-9) was used in the research process.

Application In Synthesis of (2R,3S,4S,5S)-5-(Acetoxymethyl)tetrahydrofuran-2,3,4-triyl triacetateIn 2016, Li, Guo-Xing;Morales-Rivera, Christian A.;Wang, Yaxin;Gao, Fang;He, Gang;Liu, Peng;Chen, Gong published 《Photoredox-mediated Minisci C-H alkylation of N-heteroarenes using boronic acids and hypervalent iodine》. 《Chemical Science》published the findings. The article contains the following contents:

A photoredox-mediated Minisci C-H alkylation reaction of N-heteroarenes with alkyl boronic acids is reported. A broad range of primary and secondary alkyl groups can be efficiently incorporated into various N-heteroarenes using [Ru(bpy)₃]Cl₂ as photocatalyst and acetoxybenziodoxole as oxidant under mild conditions. The reaction exhibits excellent substrate scope and functional group tolerance, and offers a broadly applicable method for late-stage functionalization of complex substrates. Mechanistic experiments and computational studies suggest that an intramolecularly stabilized ortho-iodobenzoyloxy radical intermediate might play a key role in this reaction system. And (2R,3S,4S,5S)-5-(Acetoxymethyl)tetrahydrofuran-2,3,4-triyl triacetate (cas: 144490-03-9) was used in the research process.
