Schaus, Scott E.; Brandes, Bridget D.; Larrow, Jay F.; Tokunaga, Makoto; Hansen, Karl B.; Gould, Alexandra E.; Furrow, Michael E.; Jacobsen, Eric N. published an article on February 20 ,2002. The article was titled 《Highly Selective Hydrolytic Kinetic Resolution of Terminal Epoxides Catalyzed by Chiral (salen)CoIII Complexes. Practical Synthesis of Enantioenriched Terminal Epoxides and 1,2-Diols》, and you may find the article in Journal of the American Chemical Society.Recommanded Product: (1S)-1-(2-chlorophenyl)ethane-1,2-diol The information in the text is summarized as follows:

The hydrolytic kinetic resolution (HKR) of terminal epoxides catalyzed by a chiral (salen)CoIII complex affords both recovered unreacted epoxide and 1,2-diol product in highly enantioenriched form. As such, the HKR provides general access to useful, highly enantioenriched chiral building blocks that are otherwise difficult to access, from inexpensive racemic materials. The reaction has several appealing features from a practical standpoint, including the use of H2O as a reactant and low loadings (0.2-2.0 mol %) of a recyclable, com. available catalyst. In addition, the HKR displays extraordinary scope, as a wide assortment of sterically and electronically varied epoxides can be resolved to ≥99% ee. The corresponding 1,2-diols were produced in good-to-high enantiomeric excess using 0.45 equiv of H2O. Useful and general protocols are provided for the isolation of highly enantioenriched epoxides and diols, as well as for catalyst recovery and recycling. Selectivity factors (krel) were determined for the HKR reactions by measuring the product ee at ca. 20% conversion. In nearly all cases, krel values for the HKR exceed 50, and in several cases are well in excess of 200. The experimental part of the paper was very detailed, including the reaction process of (1S)-1-(2-chlorophenyl)ethane-1,2-diol(cas: 133082-13-0Recommanded Product: (1S)-1-(2-chlorophenyl)ethane-1,2-diol)

In 2018,Armstrong, Roly J.; Nandakumar, Meganathan; Dias, Rafael M. P.; Noble, Adam; Myers, Eddie L.; Aggarwal, Varinder K. published 《Enantiodivergent Synthesis of Allenes by Point-to-Axial Chirality Transfer》.Angewandte Chemie, International Edition published the findings.Product Details of 78782-17-9 The information in the text is summarized as follows:

Nonracemic di-, tri-, and tetrasubstituted allenes were prepared by an enantiodivergent route using the homologation of (phenylselenyl)alkenylboronates such as I with lithiated alkyl diisopropylcarbamates generated with (+)-sparteine and s-BuLi and stereoselective oxidative syn-elimination and alkylative anti-elimination reactions as key steps. Nonracemic boronic esters such as II were prepared by homologation of α-seleno alkenyl boronic esters such as I with lithiated diisopropylcarbamates such as 4-MeOC6H4CH2CH2CH2OCONi-Pr2. Syn-elimination of II using mCPBA yielded the nonracemic (P)-allene III in >99% enantiospecificity, while anti-elimination of II by alkylation with MeOTf in CH2Cl2 followed by NaHCO3 in MeOH yielded (M)-allene IV in 98% enantiospecificity. By employing either oxidative or alkylative conditions, both syn and anti elimination could be achieved with complete stereospecificity. The process enables the synthesis of either M or P allenes from a single isomer of a point-chiral precursor and can be employed for the enantioselective assembly of di-, tri-, and tetrasubstituted allenes.

In 2018,Yamamoto, Takeshi; Murakami, Ryo; Komatsu, Satoko; Suginome, Michinori published 《Chirality-Amplifying, Dynamic Induction of Single-Handed Helix by Chiral Guests to Macromolecular Chiral Catalysts Bearing Boronyl Pendants as Receptor Sites》.Journal of the American Chemical Society published the findings.Formula: C9H11NO The information in the text is summarized as follows:

Helical chirality of poly(quinoxaline-2,3-diyl)s bearing a boronyl pendant at the 5-position of the quinoxaline ring was induced by condensation with chiral guests such as a diol, diamine, and amino alc. Reversible induction of a single-handed helical structure was achieved by using less than an equimolar amount of chiral amino alcs. to the boronyl pendants. Majority-rule-effect-based chiral amplification on the polyquinoxaline main chain was demonstrated with chiral amino alcs. with low enantiomeric excess (ee). The helical macromol. scaffold whose helicity was thus induced was utilized in palladium-catalyzed asym. silaboration of meso-methylenecyclopropane (up to 92% ee) by introducing (diarylphosphino)phenyl pendants at their side chains. In the experiment, the researchers used (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7Formula: C9H11NO)

(1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol(cas: 126456-43-7) belongs to anime. Amines characteristically form salts with acids; a hydrogen ion, H+, adds to the nitrogen. With the strong mineral acids (e.g., H2SO4, HNO3, and HCl), the reaction is vigorous. Salt formation is instantly reversed by strong bases such as NaOH. Neutral electrophiles (compounds attracted to regions of negative charge) also react with amines; alkyl halides (R′X) and analogous alkylating agents are important examples of electrophilic reagents.Formula: C9H11NO

In 2019,Journal of Molecular Liquids included an article by Abdul Samat, Nurul Fatin Nabilah; Yusoff, Rozita Binti; Aroua, Mohamed Kheireddine; Ramalingam, Anantharaj; Kassim, Mohd Azlan. HPLC of Formula: 534-03-2. The article was titled 《Solubility of CO2 in aqueous 2-amino-1, 3-propanediol (Serinol) at elevated pressures》. The information in the text is summarized as follows:

In this work, aqueous 2-amino-1, 3-propanediol solution (serinol) was investigated as a potential solvent for CO2 capture from different gas streams. Prior to CO2 solubility experiments, a qual. prediction technique was performed on serinol to ensure its potentiality as a CO2 capture solvent. This was done using COSMO-RS approach based on quantum chem. calculations Based on this approach, serinol showed good affinity towards hydrogen-bond donors which proved to be beneficial in developing intermol. interaction between serinol and CO2. The solubility of CO2 in serinol was then investigated at serinol concentrations ranging from 1 M to 3 M, temperatures ranging from 313.15 K to 353.15 K and CO2 partial pressures ranging from 1034.31 kPa to 2068.43 kPa. The solubility of CO2 in serinol reached a highest value of 1.64 mol of CO2/mol of serinol when the serinol concentration was 1 M, at 313.15 K and 2068.43 kPa. Meanwhile, Henry’s law constant of CO2 in serinol was calculated using N2O analogy at 313.15 K and 333.15 K for molar concentrations of 1 M and 3 M of serinol. Results showed that the phys. solubility of CO2 in serinol increased as the temperature and the concentration of the solution decreased. The lowest value of Henry’s law constant of CO2 was 599.4 kPa·m3·kmol-1, for 1 M of serinol at 313.15 K. In the part of experimental materials, we found many familiar compounds, such as 2-Aminopropane-1,3-diol(cas: 534-03-2HPLC of Formula: 534-03-2)

And the article was published in Macromolecules (Washington, DC, United States) in 2019. Name: 3-Bromopropan-1-ol The author mentioned the following in the article:

Photochem. cross-linked shape-memory polymer (SMP) materials have been achieved by functionalizing chain-ends of star-shaped poly(ε-caprolactone) (PCL) with 7-hydroxypropoxy-4-methylcoumarin followed by photodimerization of these end-groups. The kinetics of the network formation in function of the photosensitizer concentration has been studied by swelling experiments and rheol. Thanks to the design of a dedicated homemade mold, highly reproducible irradiation conditions have been achieved allowing to study the network formation and properties, especially the shape-memory properties, in relation to the coumarin dimerization degree as determined by Raman spectroscopy. In optimized conditions, PCL-based SMP materials exhibiting high fixity and recovery have been achieved in remarkably short irradiation time, typically 5 min. In addition, the precise control of the network cross-link d. with the irradiation time, so as the high stability of the formed networks toward temperature variations was also demonstrated allowing the fine-tuning of the network properties by the irradiation process. Finally, the reversible character of the coumarin dimerization under light irradiation of appropriate wavelength has been quantified by Raman spectroscopy. The dimer photocleavage allows the photoreconfiguration of the networks offering the ability to modify the “”permanent”” shape of the SMP material, while preserving the excellent shape-memory properties. In the experiment, the researchers used 3-Bromopropan-1-ol(cas: 627-18-9Name: 3-Bromopropan-1-ol)
