We report on a new class of P-O monophosphite ligands (designated 3a-k) with a double six-membered-ring backbone onto which are attached additional groups and on applications of their Rh complexes in the hydrogenation of enamides, alpha-dehydroamino acid esters, dimethyl itaconate, and beta-(acylamino)acrylates. Our results demonstrate that the Rh complexes with ligands 3a-k exhibit high enantioselectivity and reactivity in asymmetric hydrogenation reactions. An ee value of up to 98.0% was obtained for the hydrogenation of alpha-dehydroamino acid esters, and the ee values were all over 99% for the other three types of substrate, with a turnover number of up to 5000.

Reference of 1806-29-7, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 1806-29-7, C12H10O2. A document type is Article, introducing its new discovery.

Three ligands L1, L2, and L3 with 2, 4, and 6 1,4,7,10-tetraazacyclododecane (cyclen) moieties attached to a cyclotriphosphazene core, respectively, were synthesized, and oxidation activities of their CuII complexes were investigated. Aerobic oxidation of catechol by these complexes follows an intramolecular dinuclear pathway with significant cooperativity (i.e., theta ? 1.5 out of a maximum of 2 for two potential substrate binding sites) and kinetic constants (i.e., kcat = 17.5 × 10?3 s?1, Km = 2.8 mm, and quite remarkable catalytic specificity kcat/Km 12.5 m?1 s?1 per di-Cu center), while that by untethered CuII?cyclen follows a bimolecular dinuclear pathway without noticeable cooperativity (theta = 0.96) and fourfold lower kcat, despite their similar dinuclear mechanisms. The proximity of CuII centers is suggested by EPR spectra and relaxations, showing a broad spectral component particularly in Cu6L3. Thermodynamic parameters also indicate the significance of multi-CuII sites in the oxidative catalysis. Air is a more specific oxidation agent for the representative complex Cu2L1, showing 3.2-fold higher catalytic specificity kcat/Km than H2O2 toward a catechol substrate. The research provides further molecular basis for future design of O2/H2O2-specific oxidation of multi-domain Cu complexes.

We reported the discovery of potent antioxidants based on magnolol, a naturally occurring biphenolic obtained from the bark of Magnolia officinalis. The allylmagnolols 3a,b were synthesized via O-alkylation of the biphenols followed by Claisen rearrangement. In-vitro using enhanced chemiluminescence (CL) and flow cytometric assays in whole cells revealed that both 3a and 3b displayed promising free radical scavenging effects in PMA- and LPS-stimulated models as compared with magnolol. Further DNA labeling analysis for cytotoxicity indicated that these analogues show no cytotoxic effects for the scavenging of the oxygen-derived free radicals under PMA-stimulated concentrations. The results from 3,3?-bisallylmagnolol (3b) suggested that the naturally occurring constituent was suitable to be a lead compound for the development of potential antioxidants for certain diseases.

Di(alkylene phosphites) derived from biphenyl-2,2?-diol were synthesized, and their structure and some chemical properties (oxidation, sulfurization, nucleophilic reactions, and complex formation) were studied. The chemical properties of the phosphites were found to depend both on the structure of the matrix and on the structure of the phospha cycle.

1,3,7,9-Tetrabutylpyrimido<5,4-g>pteridine-2,4,6,8(1H,3H,7H,9H)-tetraone 5-oxide 1 transfers its N-oxide oxygen to phenols, i.e., phenol 5, p-cresol 6, L-tyrosine methyl ester 7, and p-hydroxyacetanilide (acetaminophen) 8, under photochemical conditions to give the corresponding dihydric phenols as major products without any accompanying photochemical intramolecular rearrangements of the N-oxide group taking place.This oxygenation is reasonably explained in terms of a photo-induced single electron transfer (SET) followed by oxygen-atom transfer (the SET mechanism) which occurs via the initial formation of a charge-transfer complex between compound 1 and the phenols employed.Comparative experiments with 3,10-dibutylisoalloxazine 5-oxide 3 and 3-methylpyridazine 2-oxide 4 well demonstrate the simplicity and the mechanistic characteristics of the photochemistry of compound 1.
