Borkar, Vitthal T. published the artcileA novel ternary approach to quantitatively assess the reactivity of nitroaniline regioisomers by investigation of rapid iodination kinetics using hydrodynamic voltammetry, reduction propensities from polarography, and binding affinities from molecular docking simulations, Synthetic Route of 105752-04-3, the main research area is nitroaniline regioisomer iodination reaction mechanism kinetic study mol docking.

A novel ternary approach to assess the reactivity of nitroaniline regioisomers on a quant. scaffold has been manifested on the basis of three complementary tenets: kinetics, polarog., and mol. docking. Data from investigation of rapid iodination kinetics of nitroaniline regioisomers by hydrodynamic voltammetry in aqueous medium, reduction propensities of these regioisomers from polarog., and their binding affinities with hypoxanthine-guanine phophoribosyltransferase (HPRT1) from mol. docking simulations lead to inferences regarding their reactivity that agree in entirety. The exptl. determined magnitudes of the specific reaction rates, energies of activation, collision frequencies, entropies of activation from kinetic studies, and reduction propensities of nitroaniline regioisomers from polarograms when complemented with in silico binding energies of these regioisomer ligands with the receptor enzyme, assess their relative reactivities in unison on a quant. scaffold. This novel ternary approach unambiguously assesses the reactivity of the regioisomers of nitroaniline as 4-nitroaniline > 2-nitroaniline > 3-nitroaniline.

Li, Yan published the artcileLigand-Controlled Cobalt-Catalyzed Regiodivergent Alkyne Hydroalkylation, Category: iodides-buliding-blocks, the main research area is alkyne haloalkane cobalt catalyst regioselective hydroalkylation; alkene preparation.

Herein, a ligand-controlled cobalt-catalyzed regiodivergent alkyne hydroalkylation was reported. The sensible selection of bisoxazoline and pyridine-oxazoline ligands led to reliable and predictable protocols that provided (E)-1,2-disubstituted and 1,1-disubstituted alkenes with high E/Z stereoselectivity and regioisomeric ratio starting from identical terminal alkyne and alkyl halide substrates and produced trisubstituted alkenes in the case of internal alkynes. This method exhibited a broad scope for terminal and internal alkynes with a wide range of activated and unactivated alkyl halides and shows excellent functional group compatibility.

Deng, Boxin published the artcileImidazolium-based organoiridium-functionalized periodic mesoporous organosilica boosts enantioselective reduction of α-cyanoacetophenones, α-nitroacetophenones, and β-ketoesters, HPLC of Formula: 63131-30-6, the main research area is imidazolium organoiridium enantioselective reduction.

An imidazolium-based, organoiridium-functionalized periodic mesoporous organosilica is developed through complexation of chiral pentafluorophenylsulfonyl-1,2-diphenylethylenediamine and organoiridium-functionalized periodic mesoporous organosilica. Structural analyses and characterizations of catalyst reveal well-defined single-site iridium active species within its organosilicate network. Electron microscopy confirms a highly ordered dimensional-hexagonal mesostructure. This bifunctional heterogeneous catalyst displays excellent catalytic performance in the enantioselective reduction of α-cyano and α-nitroacetophenones. As expected, incorporation of imidazolium-functionality within hydrophobic periodic mesoporous organosilica promotes catalytic activity and enantioselectivity. In addition, this heterogeneous catalyst can be recovered and reused for at least eight times without loss of its catalytic activity. Furthermore, the approach described here can also construct another organoiridium-functionalized periodic mesoporous organosilica through postcoordination of chiral methylsulfonyl-1,2-diphenylethylenediamine, which provides excellent catalytic activity and enantioselectivity in the enantioselective reduction of β-ketoesters. The method presented here offers a potential way for immobilizing various chiral ligands to construct chiral organometal-functionalized periodic mesoporous organosilicas.

Rocca, P. published the artcileFirst metalation of aryl iodides: directed ortho-lithiation of iodopyridines, halogen-dance, and application to synthesis, Category: iodides-buliding-blocks, the main research area is metalation iodopyridine regiochem rearrangement; ortho lithiation iodopyridine regiochem rearrangement; aryl iodide metalation regiochem rearrangement; perlolidine preparation; diazaphenanthrene preparation; carboline preparation.

Metalation of iodopyridines was successfully achieved by LDA at low temperature In many cases, lithiation is ortho directed by the iodo group which subsequently ortho-migrates very fast to give stabilized iodolithiopyridines. This procedure was applied to 2-fluoro- and 2-chloro-3-iodopyridines, 3-fluoro-4-iodopyridine, and 2-chloro-3-fluoro-4-iodopyridine. The resulting lithio intermediates were obtained in high yields before being reacted with electrophiles leading to various polysubstituted pyridines. Some of these iodopyridines were used as key mols. for the preparation of fused polyaromatic alkaloids. Thus, perlolidine (I), δ-carbolines, and 2,10-diazaphenanthrenes were readily prepared in few steps taking advantage of the iodo reactivity for heteroring cross-coupling. Coupling of [2-(pivaloylamino)phenyl]boronic acid with 2-fluoro-4-iodo-3-pyridinecarboxaldehyde gave I.

Davis, Tyler A. published the artcileChiral proton catalysis of secondary nitroalkane additions to azomethine: synthesis of a potent GlyT1 inhibitor, Recommanded Product: Benzyl 3-iodoazetidine-1-carboxylate, the main research area is enantioselective synthesis GlyT1 inhibitor aza Henry nitroazetidine amidine organocatalyst.

The first enantioselective synthesis of a potent GlyT1 inhibitor is described. A 3-nitroazetidine donor is used in an enantioselective aza-Henry reaction catalyzed by a bis(amidine)-triflic acid salt organocatalyst, delivering the key intermediate with 92% ee. This adduct is reductively denitrated and converted to the target through a short sequence, thereby allowing assignment of the absolute configuration of the more potent enantiomer.

Kurasaki, Haruaki published the artcileLpxC Inhibitors: Design, Synthesis, and Biological Evaluation of Oxazolidinones as Gram-negative Antibacterial Agents, Synthetic Route of 105752-04-3, the main research area is oxazolidinone derivative preparation LpxC inhibitor antibacterial; Antibacterial; Gram-negative bacteria; LpxC; oxazolidinone; scaffold hopping.

Herein we report a scaffold-hopping approach to identify a new scaffold with a zinc binding headgroup. Structural information was used to give novel oxazolidinone-based LpxC inhibitors. In particular, the most potent compound, 23j, showed a low efflux ratio, nanomolar potencies against E. coli LpxC enzyme, and excellent antibacterial activity against E. coli and K. pneumoniae. Computational docking was used to predict the interaction between 23j and E. coli LpxC, suggesting that the interactions with C207 and C63 contribute to the strong activity. These results provide new insights into the design of next-generation LpxC inhibitors.
