The Pd-catalyzed direct C(sp2)-H arylation of aromatic ketones using a transient directing group is described. The ketimine/carboxylate bidentate directing group in situ generated from aromatic ketone and glycine enabled a palladium-catalyzed ortho-C-H arylation, which shows extensive substrate compatibility.

Reference of 70918-54-6, New Advances in Chemical Research in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 70918-54-6, Name is (S)-1,4-Benzodioxane-2-carboxylic acid. In a Article, once mentioned of 70918-54-6.

The synthesis of some cyclic and open analogues of 2-(2,6-dimethoxyphenoxyethylaminomethyl)-1,4-benzodioxane (1, WB 4101) is described. The blocking activity of this compound and its analogues (1-5) was determined on the pre- and postsynaptic alpha-adrenoceptors of isolated rat vas deferens to investigate the structural requirements for conpetitive alpha-adrenoceptor occupancy by antagonists of the benzodioxane class. The activities of 1-5 at the presynaptic alpha-adrenoceptor were not significantly different whereas there were differences among the compounds of at least two orders of magnitude at the postsynaptic alpha-adrenoceptor. This clearly indicates that the structural requirements at the presynaptic receptor level are less restrictive than those required by the postsynaptic alpha-adrenoceptor. The symmetric analogues 3 and 4 were significantly weaker postsynaptic alpha-antagonists compared to 1. On the other hand, 2 and 5 displayed a very high postsynaptic activity, almost comparable to that of 1. These findings might suggest that the antagonists of the benzodioxane class do not bind at two identical aromatic sites symmetrically arranged around the anionic site of the alpha-adrenoceptor. Indeed, they might indicate that the benzodioxane binding site(s) incorporates two areas with very similar but not identical structural requirements. Furthermore, the very high activity of 5 may suggest that the benzodioxane nucleus is not essential to activity.

A series of pyrazoles derived from the substituted enaminones were synthesized and were evaluated for antimicrobial activity. All the compounds were characterized by the spectral data and elemental analysis. The synthesized compounds were initially screened for their antimicrobial activity against ATCC 6538, NCTC 10400, NCTC 10418, and ATCC 27853. During initial screening, compounds (P1, P6, and P11) presented significant antimicrobial activity through disc diffusion assay. These compounds were further evaluated for antimicrobial activity at different time points against Gram-positive and Gram-negative bacteria and presented significant activity for 6 hours. The activity was found to be greater against Gram-positive bacteria. In contrast at 24 hours, the activity was found only against Gram-positive bacteria except compound (P11), showing activity against both types of bacteria. Compound (P11) was found to have highest activity against both Gram-positive and Gram-negative bacteria.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Vibronically-resolved S1-S0 electronic spectra of 2-(p-fluorophenyl)ethanol have been studied by use of laser-induced fluorescence excitation and dispersed fluorescence spectroscopic methods in a supersonic free jet expansion. Two conformational isomers of the molecule are identified, and with the aid of the predictions of quantum chemistry calculations these are assigned to gauche and anti conformers. The assignments are corroborated by analyzing the vibronic features in the dispersed fluorescence spectra of the two conformers and their TDDFT predicted electronic transition energies. Energetic and spectral features of the conformers are compared with those of the parent molecule 2-phenylethanol.

With the emergence of multidrug-resistant strains of Mycobacterium tuberculosis there is a pressing need for new oral drugs with novel mechanisms of action. Herein, we describe the identification of a novel morpholino-thiophenes (MOT) series following phenotypic screening of the Eli Lilly corporate library against M. tuberculosis strain H37Rv. The design, synthesis, and structure-activity relationships of a range of analogues around the confirmed actives are described. Optimized leads with potent whole cell activity against H37Rv, no cytotoxicity flags, and in vivo efficacy in an acute murine model of infection are described. Mode-of-action studies suggest that the novel scaffold targets QcrB, a subunit of the menaquinol cytochrome c oxidoreductase, part of the bc1-aa3-type cytochrome c oxidase complex that is responsible for driving oxygen-dependent respiration.
