Li, Renhe published the artcileRedox-Neutral ortho Functionalization of Aryl Boroxines via Palladium/Norbornene Cooperative Catalysis, Quality Control of 209919-30-2, the publication is Chem (2019), 5(4), 929-939, database is CAplus and MEDLINE.

A redox-neutral ortho functionalization of aryl boroxines via Pd/NBE catalysis was reported. An electrophile, such as carboxylic acid anhydrides or O-benzoyl hydroxylamines, was coupled at the boroxine ortho position, and a proton as the second electrophile was introduced at the ipso position. This reaction did not require extra oxidants or reductants and avoided stoichiometric bases or acids, thereby tolerating a wide range of functional groups. In particular, orthogonal chemoselectivity between aryl iodide and boroxine moieties was demonstrated, which could be used to control reaction sequences. Finally, a deuterium-labeling study supported the ipso protonation pathway. This unique mechanistic feature could inspire the development of a new class of Pd/NBE-catalyzed transformations.

Li, Fengqing published the artcileJ-aggregation in porphyrin nanoparticles induced by diphenylalanine, Quality Control of 42074-68-0, the publication is Journal of Solid State Chemistry (2017), 86-92, database is CAplus.

In this report, L-diphenylalanine-decorated tetraphenylporphyrin (TPPtFF_C) was synthesized and self-assembled into regular nano-architectures. The morphol. of the assemblies varied with the concentration of TPPtFF_C. The absorption spectra of the nanoparticles show the Soret band merges with the Q bands and redistributes with great red-shift, indicative of the formation of J-aggregates of the porphyrin mols. The fluorescence emission of the nanoparticles is merged and red-shifted to near-IR region. Studies of absorption and fluorescence spectra reveal an indispensable role of diphenylalanine group in the formation of J-aggregates. The Raman spectra disclose that diprotonation of the porphyrin core contributes to delocalized coherent excited states in the nanoparticles. The pos. Cotton effect in CD spectra corresponding to the Soret band of TPPtFF_C in solution confirms the formation of J-aggregates with right-handed chirality of the dipole moment. This report will shed light on the rational design of porphyrin-peptide conjugates to mimic naturally light-harvesting complexes.

Herein, diastereo- and regioselective synthesis of trisubstituted alkenes via nickel-catalyzed benzylation and isomerization of terminal olefins with benzyl chlorides in presence of trimethylsilyl triflate and trimethylamine additives was described. Control experiments provided evidence for a mechanism involving branched-selective Heck-type benzylation that overrides substrate control, followed by trans-selective 1,3-hydrogen shift.

The effect of the cationic surfactants decamethoxine and miramistin on the physicochem. properties of the natural flavonoids quercetin and rutin is studied spectrophotometrically in the range of physiol. pH values. It is established that the interaction with these cationic surfactants changes the spectral characteristics of the flavonoids in solutions and essentially increases their adsorption on the surface of highly dispersed silica as compared with their aqueous solutions It is shown that the efficiency of flavonoid adsorption from decamethoxine and miramistin solutions is governed by solution pH, flavonoid hydrophobicity, and the nature of a cationic surfactant.

Baud, Matthias G. J. published the artcileNew Synthetic Routes to Triazolo-benzodiazepine Analogues: Expanding the Scope of the Bump-and-Hole Approach for Selective Bromo and Extra-Terminal (BET) Bromodomain Inhibition, SDS of cas: 209919-30-2, the publication is Journal of Medicinal Chemistry (2016), 59(4), 1492-1500, database is CAplus and MEDLINE.

We describe new synthetic routes developed toward a range of substituted analogs of bromo and extra-terminal (BET) bromodomain inhibitors I-BET762/JQ1 based on the triazolo-benzodiazepine scaffold. These new routes allow for the derivatization of the methoxyphenyl and chlorophenyl rings, in addition to the diazepine ternary center and the side chain methylene moiety. Substitution at the level of the side chain methylene afforded compounds targeting specifically and potently engineered BET bromodomains designed as part of a bump and hole approach. We further demonstrate that marked selectivity for the second over the first bromodomain can be achieved with an indole derivative that exploits differential interaction with an aspartate/histidine conservative substitution on the BC loop of BET bromodomains.
