An iridium-catalyzed transfer hydrogenation of N-heteroarenes to access a series of substituted 1,2,3,4-tetrahydroquinoline derivatives in excellent yields is disclosed. This transformation is distinguished with water-soluble and air-stable iridium complexes as the catalyst, formic acid as the hydrogen source, mild reaction conditions, and broad functional group compatibility.

The selective hydrogenation of nitro compounds into their corresponding azo compounds is challenging in organic synthesis. In this study, we have developed a facile and efficient catalytic system for the transformation of nitro compounds into azo compounds under mild conditions over a heterogeneous cobalt catalyst (Co-N-x/C-800-AT). The Co-N-x/C-800-AT catalyst was found to be highly active for the reductive-coupling of nitro compounds into azo compounds in ethanol at 110 degrees C and 2.5 bar H-2 pressure with the addition of NaOH as an additive, affording structurally-diverse azo compounds with satisfactory yields (70.4-98.3%). The developed method demonstrated several advantages such as high catalytic activity and high selectivity with tolerance to other functional groups and high stability.

An unprecendented chiral sulfide catalyzed desymmetrizing enantioselective chlorination is disclosed. Various aryl-tethered diolefins and diaryl-tethered olefins afforded teralins and tricyclic hexahydrophenalene derivatives, respectively, bearing multiple stereogenic centers in high yields with excellent enantio- and diastereoselectivities. In contrast, the tertiary amine catalyst (DHQD)(2)PHAL led to a diastereomeric product. The products could be transformed into a variety of compounds, such as spiro-N-heterocycles.

In the current study, a series of macrocyclic tripeptide Schiff bases 2-6 were synthesized by using macrocyclic tripeptide hydrazide 1 as starting material. Treatment of hydrazide 1 with active carbonyl cycloalkanones gave cycloalkanone hydrazines 2a-2d. Also, condensation of 1 with aromatic and heterocyclic aldehydes, or aromatic and heterocyclic acetyl derivatives afforded the corresponding Schiff base candidates 3a-3e, 4a-4c, 5a-5c, and 6a-6c, respectively.

I found the field of Chemistry very interesting.

Described is a physical organic study of the reduction of three sets of carbonyl compounds by the NADPH-dependent enzyme Clostridium acetobutylicum alcohol dehydrogenase (CaADH). Previous studies in our group have shown this enzyme to display broad substrate promiscuity, yet remarkable stereochemical fidelity, in the reduction of carbonyl compounds, including alpha-, beta- and gamma-keto esters ( d -stereochemistry), as well as alpha,alpha-difluorinated-beta-keto phosphonate esters ( l -stereochemistry). To better mechanistically characterize this promising dehydrogenase enzyme, we report here the results of a Hammett linear free-energy relationship (LFER) study across three distinct classes of carbonyl substrates; namely aryl aldehydes, aryl beta-keto esters and aryl trifluoromethyl ketones. Rates are measured by monitoring the decrease in NADPH fluorescence at 460 nm with time across a range of substrate concentrations for each member of each carbonyl compound class. The resulting v (0) versus [S] data are subjected to least-squares hyperbolic fitting to the Michaelis-Menton equation. Hammett plots of log( V (max) ) versus sigma (X) yield the following Hammett parameters: (i) for p -substituted aldehydes, rho = 0.99 +/- 0.10, rho = 0.40 +/- 0.09; two domains observed, (ii) for p -substituted beta-keto esters rho = 1.02 +/- 0.31, and (iii) for p -substituted aryl trifluoromethyl ketones rho = -0.97 +/- 0.12. The positive sign of rho indicated for the first two compound classes suggests that the hydride transfer from the nicotinamide cofactor is at least partially rate-limiting, whereas the negative sign of rho for the aryl trifluoromethyl ketone class suggests that dehydration of the ketone hydrate may be rate-limiting for this compound class. Consistent with this notion, examination of the (13) C NMR spectra for the set of p -substituted aryl trifluo-romethyl ketones in 2% aqueous DMSO reveals significant formation of the hydrate ( gem -diol) for this compound family, with compounds bearing the more electron-withdrawing groups showing greater degrees of hydration. This work also presents the first examples of the CaADH-mediated reduction of aryl trifluoromethyl ketones, and chiral HPLC analysis indicates that the parent compound alpha,alpha,alpha-trifluoroacetophenone is enzymatically reduced in 99% ee and 95% yield, providing the ( S )-stereoisomer, suggesting yet another compound class for which this enzyme displays high enantioselectivity.

Mono- or di-substituted imidazole derivatives were synthesized using a one-pot, two-step strategy. All imidazole derivatives were tested for AChE and BChE inhibition and showed nanomolar activity similar to that of the test compound donepezil and higher than that of tacrine. Structure activity relationship studies, docking studies to on X-ray crystal structure of AChE with PDB code 1B41, and adsorption, distribution, metabolism, and excretion (ADME) predictions were performed. The synthesized core skeleton was bound to important regions of the active site of AChE such as the peripheral anionic site (PAS), oxyanion hole (OH), and anionic subsite (AS). Selectivity of the reported test compounds was calculated and enzyme kinetic studies revealed that they behave as competitive inhibitors, while two of the test compounds showed noncompetitive inhibitory behavior. ADME predictions revealed that the synthesized molecules might pass through the blood brain barrier and intestinal epithelial barrier and circulate freely in the blood stream without binding to human serum albumin. While the toxicity of one compound on the WS1 (skin fibroblast) cell line was 1790 mu M, its toxicity on the SH-SY5Y (neuroblastoma) cell line was 950 mu M.
