Lorenzini, F; Lagueux-Tremblay, PL; Kayser, LV; Anderson, E; Arndtsen, BA in [Lorenzini, Fabio; Lagueux-Tremblay, Pierre-Louis; Kayser, Laure V.; Anderson, Ethan; Arndtsen, Bruce A.] McGill Univ, Dept Chem, 801 Sherbrooke St W, Montreal, PQ H3A 0B8, Canada published Synthesis, structure and palladium coordination of ambiphilic, pyridine- and phosphine-tethered N-boryl imine ligands in 2019.0, Cited 56.0. The Name is Phenyl(pyridin-2-yl)methanone. Through research, I have a further understanding and discovery of 91-02-1.

We describe here the synthesis and structural characterization of two new classes of ambiphilic, N-boryl imine ligands, wherein boron is associated with a Lewis basic imine nitrogen. These ligands can be easily generated in two steps from the corresponding pyridinyl- and phosphinyl-tethered aldehydes. B-11 NMR analysis suggests the association of the Lewis acidic boron to either the pyridine unit or via intermolecular acid/base interactions with the imine. Both of these ligands can coordinate to palladium, and their structures were confirmed by X-ray crystallography.

A novel pH-activatable fluorescent probe, 1-(propan-2-yl)-9H-pyrido[3,4-b]indole-3-carboxylic acid (L-1), based on beta-carboline derivatives, has been developed, which displays significant fluorescent response toward pH variation with high selectivity, good photo-stability and favorable pKa value. Moreover, L-1 can dynamically monitor the release of protons during ester hydrolysis reaction in consistent with enzymatic kinetics manner.

Purpose: We investigated Nw-hydroxy L-Arginine (NOHA) predictive response in serous ovarian carcinoma based on estrogen-hormone receptor expression status; and assessed the distinctive NOHA response between estrogen-receptor-negative (ER-) tumor subtypes of ovarian and breast cancer. Materials/methods: Three-dimensional (3D) spheroids models of ER- and estrogen-receptor-positive (ER+) from breast and ovarian tumor, cultured for 9 weeks, were assayed for cellular levels of inducible nitric oxide synthase (NOS2), nitric oxide (as total nitrite) and L-Arginine, and compared to NOHA in culture medium. Statistical difference was set at p < 0.01. Results: Nine-week in vitro studies showed a progressive NOHA reduction in culture medium by at least 0.4-0.8 fold, and 0.65-0.92 fold only in the ER-breast tumor and ER-ovarian tumor 3D spheroids, respectively; with increases in cellular NOS2 and nitric-oxide levels, by at least 1.0-2.45 fold in both ER-tumor subtype 3D spheroids (p < 0.01; n = 6). Within ER-subtypes, medium NOHA decreased by >= 38.9% in ovarian cancer over breast cancer 3D-spheroids, with cellular increases in NOS2 (by >= 17.4%), and nitric oxide (by >= 18.8%). Cellular L-Arginine to medium NOHA ratio was higher, and by at least 6.5-22.5 fold in ER-breast tumor 3D-spheroids, and at least 10-70 fold in ER-ovarian tumor 3D spheroids, than in ER+ and control conditions; and was >= 48% higher in ER-ovarian cancer than in ER-breast cancer 3D-spheroids. Conclusions: The present study shows NOHA as a sensitive and selective indicator differentiating and distinguishing ER-subtypes based on the tumor grade.

A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.

Efficient access to diverse screening compounds with desirable, lead-like properties can be a bottleneck in early drug discovery and chemical biology. Herein we present an efficient, rapid route to three structurally distinct classes of compounds (A-C) from a single precursor, which in turn is available through a one-pot Petasis 3-component reaction/Diels-Alder cascade reaction. We demonstrate the versatility of the approach through the synthesis of 35 exemplary compounds from the three classes, as well as by the production of 2188 final compounds, which have been included in the Joint European Compound Library of the European Lead Factory.

Herein, the development of a visible-light-induced catalytic system to achieve the decarboxylative acylation of pyridine N-oxides with alpha-oxocarboxylic acids, at room temperature and using the organic dye fluorescein dimethylammonium as a new type of photocatalyst, is reported. A series of 2-arylacylpyridine N-oxides were selectively synthesized in moderate to good yields by controlling the polarity of the reaction solvent. The developed strategy was successfully applied in the synthesis of an important intermediate of the drug, acrivastine, on a gram scale. Notably, this is the first time that fluorescein dimethylammonium has been used to catalyze the Minisci-type C-H decarboxylative acylation reaction. The mechanism of decarboxylative acylation was studied by capturing adducts of acyl radicals and 1,1-diphenylethylene to confirm a radical mechanism. The disclosed catalytic system provides a green synthetic strategy for decarboxylative acylation without the use of additional oxidants or metal catalysts.

Metal precursors [(arene)MCl2](2) (arene = p-cymene, Cp*; M = Ru, Rh and Ir) on reacting with 9-fluorenone derivative ligands L1, L2 and L3 resulted in the formation of mononuclear bidentate cationic N boolean AND N bonded complexes. The biological studies of these complexes such as antibacterial activity studies (against Gram-positive and Gram-negative bacteria) revealed significant antibacterial activity with complexes 4, 7 and 9 having the highest activity potency (in-vitro). Whilst for DNA-binding studies, the results revealed that complexes 4 and 5 displayed significant changes in their spectral features upon addition of SM-DNA, thus, indicating that these complexes bind to DNA with a significant affinity.

An unprecedented example of a NHC-catalyzed acylation reaction promoted by an oxidant CCl3CN is described. This protocol features several advantages, including mild reaction conditions, broad substrate scope, and easy operation. In addition, low cost, low boiling point, and small molecular weight allow CCl3CN to be an attractive and amenable oxidant. Meanwhile, this formal dehydrogenative coupling reaction of aldehydes and alcohols involves a hydride transfer process.

Combining biological and small-molecule catalysts under a chemoenzymatic manifold presents a series of significant advantages to the synthetic community. We report herein the successful development of a two-step/single flask synthesis of gamma-lactones through the merger of Umpolung catalysis with a ketoreductase-catalyzed dynamic kinetic resolution, reduction, and cyclization. This combined approach delivers highly enantio- and diastereoenriched heterocycles and demonstrates the feasibility of integrating NHC catalysis with enzymatic processes.
