We report an efficient enantioselective conjugate addition of photogenerated alpha-amino radicals to Michael acceptors catalyzed by a newly prepared chiral-at-metal rhodium complex. This protocol shows that a single Rh(iii) complex can serve not only as a Lewis acid but also as a photoredox catalyst to control the stereoselectivity during the bond formation.

An ab initio calculation of the title molecule was performed to interpret previously observed electronic spectra of the title system. Since the computation concerns the isolated molecule, possible effects of solvent molecules had to be taken into account, especially for such as Rydberg states. The S3 ? S0, S2 ? S1 n, and S1n ? S0 absorption bands are (re)assigned to the excited states of the Lb, L a/CT, and nNsigma (3s) states, respectively. The minor S1a ? S0 absorption observed at the red area of the S1n ? S0 band in acetonitrile is reinterpreted as being a nNpi (CT) state. Correspondingly, the pi, nN, and aN fluorescence spectra are (re)ascribed to the excited states of the Lb, nNsigma*, and nNpi states, respectively. The nNsigma* and nN* states are found to be restricted to the equatorial and axial conformers, respectively. The exceptionally long progression of the pi fluorescence in hexane is interpreted as being due to the closeness of the La and Lb states.

Herein, the visible-light-induced dehydrogenation of N-heterocycles such as tetrahydroquinolines, tetrahydroisoquinolines, and indolines in O2-containing suspensions of a commercially available titanium dioxide photocatalyst yielding the corresponding heteroarenes is presented. 4-Amino-2,2,6,6-tetramethylpipiridinyloxyl (4-amino-TEMPO) was found to exhibit a beneficial role, as it increased the yield and improved the selectivity of the dehydrogenation reaction. Both the selectivity and the yield are further enhanced by grafting 0.1 wt % of Ni(II) ions onto the TiO2 surface. It is proposed that the basic reactant adsorbs at Lewis acid sites present at the TiO2 surface. The dehydrogenation reaction is initiated by visible-light excitation of the resulting surface complex and a subsequent single-electron transfer from the excited N-heterocycle via the conduction band of TiO2 to O2. Ni(II) ions possibly serve as an electron transfer bridge between the conduction band of TiO2 and O2, while the TEMPO derivative is assumed to act as a selective redox mediator involved in reactions of the generated reactive oxygen species.

We here report on our continued studies of ligands binding to the promising drug target angiotensin II type 2 receptor (AT2R). Two series of compounds were synthesized and investigated. The first series explored the effects of adding small substituents to the phenyl ring of the known selective nonpeptide AT2R antagonist C38, generating small but significant shifts in AT2R affinity. One compound in the first series was equipotent to C38 and showed similar kinetic solubility, and stability in both human and mouse liver microsomes. The second series was comprised of new bicyclic derivatives, amongst which one ligand exhibited a five-fold improved affinity to AT2R as compared to C38. The majority of the compounds in the second series, including the most potent ligand, were inferior to C38 with regard to stability in both human and mouse microsomes. In contrast to our previously reported findings, ligands with shorter carbamate alkyl chains only demonstrated slightly improved stability in microsomes. Based on data presented herein, a more adequate, tentative model of the binding modes of ligand analogues to the prototype AT2R antagonist C38 is proposed, as deduced from docking redefined by molecular dynamic simulations.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 226942-29-6, help many people in the next few years.Computed Properties of C9H10BrN
