Wu, Ting-Feng published the artcileZirconium-redox-shuttled cross-electrophile coupling of aromatic and heteroaromatic halides, Computed Properties of 2960-93-2, the publication is Chem (2021), 7(7), 1963-1974, database is CAplus and MEDLINE.

Herein, a homogeneous XEC method, which relied on a zirconaaziridine complex as a shuttle for dual palladium-catalyzed processes was reported. The zirconaaziridine-mediated palladium (ZAPd)-catalyzed reaction showed excellent compatibility with various functional groups and diverse heteroaromatic scaffolds. In accord with d. functional theory (DFT) calculations, a redox transmetallation between the oxidative addition product and the zirconaaziridine was proposed as the crucial elementary step. Thus, cross-coupling selectivity using a single transition metal catalyst was controlled by the relative rate of oxidative addition of Pd(0) into the aromatic halide. Overall, the concept of a combined reducing and transmetallating agent offered opportunities for the development of transition metal reductive coupling catalysis.

Two unexpected chiral organometallic triangles rather than squares from newly designed 90° chiral di-Pt-(II) acceptors were obtained through coordination-driven self-assembly. Their structures were well characterized by multinuclear NMR (¹H and ³¹P) and variable-temperature NMR experiments, ESI-TOF-MS, and elemental anal. The PM6 semiempirical mol. simulation was employed for the interpretation of the formation and stability of such chiral triangles.

Huang, Junmin published the artcilePreparation and evaluation of proline-based chiral columns, Category: naphthyridine, the publication is Analytical Chemistry (2005), 77(10), 3301-3308, database is CAplus and MEDLINE.

Chiral stationary phases made of readily available proline peptides were prepared and evaluated for general chiral separation With the proper structural elements, these columns demonstrated broad chiral selectivity. Among the 53 analytes tested, a tetraproline column resolved 31. The separations achieved for these analytes are comparable to those achieved on Whelk O2 column, while still inferior to those achieved on Daicel AD-H and OD-H columns. Number of proline units proves important for chiral recognition, because a control column made with a single proline unit is largely ineffective.

Zhu, Ming-Hui published the artcileDetosylative (Deutero)alkylation of Indoles and Phenols with (Deutero)alkoxides, Application In Synthesis of 2960-93-2, the publication is Organic Letters (2019), 21(17), 7073-7077, database is CAplus and MEDLINE.

An efficient strategy for N/O-(deutero)alkylation of indoles and phenols with alkoxides/alcs. as the alkylation reagents is described. The consecutive detosylation/alkylation transformations feature mild reaction conditions, high ipso-selectivity, and good functional group tolerance (>50 examples). A one-pot selective N-alkylation of unprotected indoles with alcs. and TsCl is also realized. The application of this method is demonstrated by the introduction of isotope-labeled (CD₃ and ¹³CH₃) groups using the readily accessible labeled alcs. and the synthesis of pharmaceuticals.

Yu, Hui published the artcileEvaluation of “Click” Binaphthyl Chiral Stationary Phases by Liquid Chromatography, Application In Synthesis of 2960-93-2, the publication is Chirality (2012), 24(5), 391-399, database is CAplus and MEDLINE.

Two click binaphthyl chiral stationary phases were synthesized and evaluated by liquid chromatog. Their structures incorporate S-(-)-1,1′-binaphthyl moiety as the chiral selector and 1,2,3-triazole ring as the spacer. These chiral stationary phases (CSPs) allowed the efficient resolution for a wide range of racemic BINOL derivatives, particularly for nonpolar diether derivatives and 3-Ph indolin-2-one analogs. The chromatog. data showed that the π-π interaction was crucial for enantiorecognition of these CSPs. Loss of enantioselectivity observed on CSP3, which are lacking the triazole ring linkage, indicated that the triazole ring linkage took part in the enantioseparation process, although it was remote from the chiral selector of the CSP. The substitution of the Ph group at 6 and 6′ positions can significantly improve the separation ability of the CSP. The chiral recognition mechanism was also studied by tracking the elution orders and studying the thermodn. parameters. Chirality 00:000-000, 2012. Copyright © 2012 Wiley Periodicals, Inc.

Lee, Yong-Kyung published the artcileSynthesis of novel chiral poly(methacrylate)s bearing urethane and cinchona alkaloid moieties in side chain and their chiral recognition abilities, Product Details of C22H18O2, the publication is Polymer (2002), 43(26), 7539-7547, database is CAplus.

Two types of new chiral methacrylates, cinchoninyl(2-methacryloyloxyethyl)carbamate (CIMOC) and cinchonidinyl(2-methacryloyloxy-ethyl)carbamate (CDMOC) were synthesized from 2-methacryloyloxyethyl isocyanate (MOI) and cinchona alkaloid such as cinchonine and cinchonidine, resp. Radical polymerizations of CIMOC and CDMOC were performed under several conditions to obtain the corresponding polymers whose specific optical rotations ([α]₄₃₅²⁵) were 84.0-89.0° and 0.39-0.72°, resp. From the results of radical copolymerizations of RMOC (CIMOC and CDMOC, M₁) with styrene (ST, M₂) or Me methacrylate (MMA, M₂), monomer reactivity ratios (r₁, r₂) and Alfrey-Price Q-e were determined: r₁ = 0.18, r₂ = 0.48, Q₁ = 0.53, e₁ = 0.92 for the CIMOC-ST system; r₁ = 0.53, r₂ = 0.26, Q₁ = 4.91, e₁ = 1.80 for the CIMOC-MMA system r₁ = 0.59, r₂ = 0.47, Q₁ = 0.86, e₁ = 0.33 for the CDMOC-ST system; r₁ = 0.28, r₂ = 0.59, Q₁ = 2.15, e₁ = 1.74 for the CDMOC-MMA system. The chiroptical properties of the copolymers were strongly influenced by co-units. Poly(RMOC)-bonded-silica gel as chiral stationary phase (CSP) was prepared for HPLC. The CSPs resolved some racemates such as mandelic acid and trans-2-dibenzyl-4,5-di(o-hydroxyphenyl)-1,3-dioxolane by HPLC. The chiral recognition ability of poly(RMOC) may be due to the interaction between some cinchona alkaloid units and the racemates and/or to secondary and higher-ordered structures of the polymer.

Dai, Zhi published the artcileSolution-phase synthesis and evaluation of tetraproline chiral stationary phases, Application of 2,2′-Dimethoxy-1,1′-binaphthalene, the publication is Chirality (2012), 24(4), 329-338, database is CAplus and MEDLINE.

Fmoc-Pro-Pro-Pro-Pro-OH and Fmoc-Pro-Pro-Pro-Pro-NMe(CH₂)₃CO₂H were prepared on multigramm scale by a solution-phase synthetic route; the two peptides were attached to (methylamino)propylated silica gel, deprotected, and acylated with pivaloyl chloride to provide silica gel-bound Me₃CCO-Pro-Pro-Pro-Pro-N(Me)CH₂CH₂CH₂R (R = silica) and Me₃CCO-Pro-Pro-Pro-Pro-NMe(CH₂)₃CONHCH₂CH₂CH₂R (R = silica) as chiral stationary phases for the separation of a variety of organic analytes. The resolution of analytes with the two chiral stationary phases prepared from tetraproline peptides were compared to the resolution of analytes by tetraproline synthesized on (methylamino)propylated silica gel; all three silica-bound tetraproline peptides had similar chromatog. performance for resolving the 53 model analytes tested. This suggests that the solution-phase synthesis of oligoprolines, which allows for the specific benefits of good batch reproducibility, selector homogeneity, and possibly low cost, is a feasible alternative to the solid-phase synthesis of oligoproline CSPs. © 2012 Wiley Periodicals, Inc.

Wu, Peng published the artcileChromatographic Resolution of α-Amino Acids by (R)-(3,3′-Halogen Substituted-1,1′-binaphthyl)-20-crown-6 Stationary Phase in HPLC, Formula: C22H18O2, the publication is Chinese Journal of Chemistry (2017), 35(7), 1037-1042, database is CAplus.

Three new chiral stationary phases (CSPs) for high-performance liquid chromatog. were prepared from R-(3,3-halogen substituted-1,1-binaphthyl)-20-crown-6 (halogen = Cl, Br and I ). The exptl. results showed that R-(3,3-dibromo-1,1-binaphthyl)-20-crown-6 (CSP-1) possesses more prominent enantioselectivity than the two other halogen-substituted crown ether derivatives All twenty-one α-amino acids have different degrees of separation on R-(3,3-dibromo-1,1-binaphthyl)-20-crown-6-based CSP-1 at room temperature The enantioselectivity of CSP-1 is also better than those of some com. R-(1,1-binaphthyl)-20-crown-6 derivatives Both the separation factors (α) and the resolution (R_s) are better than those of com. crown ether-based CSPs [CROWNPAK CR(+) from Daicel] under the same conditions for asparagine, threonine, proline, arginine, serine, histidine and valine, which cannot be separated by com. CR(+). This study proves the com. usefulness of the R-(3,3-dibromo-1,1-binaphthyl)-20-crown-6 chiral stationary phase.

Much attention was focused on developing the synthetic methods to prepare xanthene derivatives. Binaphthyl-based xanthene derivatives, e.g., I (R = H), were prepared through the oxidation of BINOLs promoted by the hypervalent iodine reagent iodosylbenzene (PhIO). Nine-membered lactones, e.g., II, were obtained through a similar oxidative reaction when iodoxybenzene (PhIO₂) was used. Addnl., one-pot reactions of BINOLs, PhIO and nucleophiles such as alcs. and amines were also investigated to provide alkoxylated products,e.g., I (R = Me). and amides, e.g, III. in good to excellent yields.
