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.

New discoveries in chemical research and development in 2021. Computed Properties of C11H15NO2, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 1745-07-9, Name is 6,7-Dimethoxy-1,2,3,4-tetrahydroisoquinoline, molecular formula is C11H15NO2.

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.

Hg cathode-free electrochemical detosylation of N,N-disubstituted p-toluenesulfonamides was successfully carried out by a constant current electrolysis using an undivided cell equipped with a platinum cathode and a magnesium anode in the presence of an arene mediator. The deprotection proceeded efficiently and selectively under neutral and mild conditions with a stoichiometric amount of electricity without the use of an Hg cathode to obtain the corresponding secondary amines in good to excellent yields.

A series of N-acyl-1,2,3,4-tetrahydroisoquinoline derivatives were synthesized and evaluated for their bradycardic activities in isolated guinea pig right atria and in urethane-anesthetized rats. These efforts resulted in identification of the compound 8a, which exhibits potent bradycardic activity with minimal influence on mean blood pressure in urethane-anesthetized rats. Oral administration of compound 8a to conscious rats revealed increased potency and prolonged duration of action when compared to Zatebradine.

The thienopyridine antiplatelet agent, ticlopidine and its analog, clopidogrel, have been shown to potentiate the action of beta-lactam antibiotics, reversing the methicillin-resistance phenotype of methicillin-resistant Staphylococcus aureus (MRSA), in vitro. Interestingly, these thienopyridines inhibit the action of TarO, the first enzyme in the synthesis of wall teichoic acid, an important cell wall polymer in Gram-positive bacteria. In the human body, both ticlopidine and clopidogrel undergo a rapid P450-dependent oxidation into their respective antiplatelet-active metabolites, resulting in very low plasma concentrations of intact drug. Herein, a series of analogs of ticlopidine and clopidogrel that would avoid oxidative metabolism were designed, prepared and evaluated as inhibitors of TarO. Specifically, we replaced the P450-labile thiophene ring of ticlopidine and clopidogrel to a more stable phenyl group to generate 2-(2-chlorobenzyl)-1,2,3,4-tetrahydro- isoquinoline) (6) and (2-chloro-phenyl)-(3,4-dihydro-1H-isoquinolin-2-yl)-acetic acid methyl ester (22), respectively. The latter molecules displayed inhibitory activity against TarO and formed the basis of a library of analogs. Most synthesized compounds exhibited comparable efficacy to ticlopidine and clopidogrel. So far, it was introduction of a trifluoromethyl group to compound 6, to generate 2-(2-trifluoromethyl-benzyl)-1,2,3,4-tetrahydro-isoquinoline (13) that exhibited enhanced activity against TarO. Compound 13 represents a novel stable inhibitor of TarO with synergistic impact on beta-lactam antibiotics against MRSA and low potential for P-450 metabolism.
