3-Bromo-1,1,1-trifluoroacetone was first disclosed as an effective indirect trifluoromethylation reagent to construct the important 3-trifluoromethyl isocoumarin skeleton. The reaction proceeds through a ligand-promoted, iridium-catalyzed ortho-selective C-H alkylation of benzoic acid and an intermolecular cyclization reaction promoted by silver acetate. A wide range of 3-trifluoromethyl isocoumarins can be easily obtained in moderate to good yields. Importantly, the isocoumarin skeleton can be easily formed in bioactive compounds, highlighting the importance of this reaction.

The studies culminating in the synthesis of two large subunits of tautomycetin are described. The first one, fragment C1-C12 that has an anti-1,3-dimethyl system and a terminal diene unit, was accomplished in 10 linear steps in 7.4% overall yield. The second one, fragment C13-C25 which bears the sensitive anhydride framework and the majority of the stereogenic centers, was prepared in 13 linear steps (longest sequence) in 8% overall yield. Among the key transformations used, a regioselective epoxide opening, a Pd-catalyzed addition of terminal alkyne to acceptor alkyne, a Mukaiyama aldol reaction, a Yamaguchi esterification, and a homemade mild di-esterification can be cited. The chosen strategies allowed good yields, stereoselectivity, reproducibility, and scalability for several important intermediates.

Nickel-catalyzed reduction of (het)arenecarboxylic acids with hydrosilanes in the presence of dimethyl dicarbonate as the activator affords the corresponding aldehydes. The role of the activator is the conversion of the acids into their anhydrides undergoing C?O cleavage. The good yields were achieved in case of substrates bearing electron-donating and electron-neutral groups.

Solvent reorganization is a major driving force of protein-ligand association, but the contribution of binding site waters to ligand affinity is poorly understood. We investigated how altered interactions with a water network can influence ligand binding to a receptor. A series of ligands of the A(2A) adenosine receptor, which either interacted with or displaced an ordered binding site water, were studied experimentally and by molecular dynamics simulations. An analog of the endogenous ligand that was unable to hydrogen bond to the ordered water lost affinity and this activity cliff was captured by molecular dynamics simulations. Two compounds designed to displace the ordered water from the binding site were then synthesized and evaluated experimentally, leading to the discovery of an A(2A) agonist with nanomolar activity. Calculation of the thermodynamic profiles resulting from introducing substituents that interacted with or displaced the ordered water showed that the gain of binding affinity was enthalpy driven. Detailed analysis of the energetics and binding site hydration networks revealed that the enthalpy change was governed by contributions that are commonly neglected in structure-based drug optimization. In particular, simulations suggested that displacement of water from a binding site to the bulk solvent can lead to large energy contributions. Our findings provide insights into the molecular driving forces of protein-ligand binding and strategies for rational drug design.

We report here the first example of cross-coupling between two different and unactivated C(aryl)-O bonds with chromium catalysis. The combination of a low-cost Cr(II) salt, 4,4′-di-tart-butyl-2,2′-dipyridyl (dtbpy) as the ligand, and magnesium as the reductant shows high reactivity in promoting the reductive cross-coupling of aryl methyl ether derivatives with aryl esters by cleavage and coupling of two different C(aryl)-O bonds under mild conditions. The formation of active low-valent Cr species by reduction of CrCl2 with Mg can be considered, which prefers to initially activate the C(aryl)-O bond of phenyl methyl ether with the chelation help of dtbpy and an o-imine auxiliary. The subsequent consecutive reduction, second C(aryl)-O activation, and reductive elimination allow for the achievement of selective cross-coupling of C(aryl)-O/C(aryl)-O bonds.

A variety of appropriately substituted internal alkynes were transformed into the corresponding cyano-substituted phenanthrenes, dihydronaphthalenes, and cyclohepta-1,3,5-trienes in moderate to excellent yields by treatment with imidazolium thiocyanate 1, which serves as an easy to handle [CN](+) precursor, in the presence of BCl3. The synthetic value of the method is additionally demonstrated by the transformation of the primarily obtained products into heavily substituted quinolines. Additionally, the dynamic properties of the prepared dibenzocyclohepta-1,3,5-trienes have been investigated.

Solvent extraction is an efficient and nondestructive approach to produce ash-free organic matters from direct coal liquefaction residue (DCLR). Isometric acetone/CS(2)mixture (IACM) was adopted to extract DCLR to produce IACM-soluble fraction (IACM-SF) with a yield of 86.5%. The IACM-SF is of ash-free and high carbon content of 90.18%. The typical structural features of IACM-SF are substituted aromatic structures, nonsubstituted condensed and biphenyl aromatic structures, alkyl bridged linkages, hydrogenated aromatic structures, and heteroatom-containing structures. Therefore, the IACM-SF is a useful and valuable carbon resource that can be used for producing aromatics and preparation of carbon materials.

HPLC of Formula: C9H10O3. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.

In the present examination, the thermochemical behavior of the lignin extracted from willow (Salix matsudana cv. Zhuliu) by deep eutectic solvents (DES) treatment (DES-lignin) with varied times were investigated with the techniques of thermogravimetric analyzer, in situ diffuse reflectance infrared pyrolysis (in situ-FTIR), and pyrolysis-gas chromatography/mass spectrometry. The results showed that thermal degradation of DES-lignin mainly occurred at 185-470 degrees C with two maximum weight loss peaks at 265 degrees C and 380 degrees C respectively, and the solid residue was 40% when terminated at 800 degrees C. The identified cluster of aromatics from in situ-FTIR was detected earlier and stronger than those of small molecular gases, suggesting cleavage of lignin intermolecular linkages dominated the initial pyrolysis process. The DES-lignin was sensitive to pyrolysis to produce aromatics. The total phenols yield from DES-lignin pyrolysis reached a maxima of 95.1% at 450 degrees C, among which phenol and guaiacol accounted for the largest proportion, i.e. 20.8% and 24.2% respectively. In addition, product distribution was remarkably affected by pyrolysis temperature and the DES treatment time used for lignin isolation.
