Unraveling the effect of two different polar solvents on the excited-state intramolecular proton transfer of 4?-methoxy-3-hydroxyflavone fluorescent dye

The fluorescence properties of 4?-methoxy-3-hydroxyflavone (M3HF) dye in different solvents were investigated through experimental (Phys. Chem. Chem. Phys., 2018, 20, 7885) and theoretical (Org. Chem. Front., 2019, 6, 218) methods. However, the intermolecular hydrogen bonds between M3HF and solvents were ignored. In this work, we investigated the effect of methanol (MeOH) and N,N-dimethylformamide (DMF) solvents on the excited-state intramolecular proton transfer (ESIPT) of M3HF fluorescent dye. In excited state (S1), the intramolecular hydrogen bonds are significantly strengthened, which can facilitate the ESIPT processes. The calculated absorption and fluorescence spectra agree well with the experimental date. The fluorescence spectra of M3HF and ESIPT tautomers (T?) were found to be sensitive to the solvent polarity. Upon photo-excitation, the electron density of the M3HF molecular is redistributed, which can provide driving force for the ESIPT. The polar solvents MeOH (hydrogen bond donor) and DMF (hydrogen bond acceptor) can form different types of intermolecular hydrogen bonds with M3HF. The two different bonding modes of intermolecular hydrogen bonds are expected to weaken the intramolecular hydrogen bond of M3HF to varying degrees. The analysis of the potential energy curves indicate that the ESIPT processes of M3HF can be hindered by the intermolecular hydrogen bonds. The intermolecular hydrogen bond of M3HF-DMF complex is weaker than that of M3HF-MeOH complex, while the potential barrier of the ESIPT process in DMF solvent is higher than that of in the MeOH solvent. This is principally because, in DMF solvent, the hydroxyl group H1 atom of M3HF can be captured by the O3 atom of DMF and form O3?H1 bond with O3 atom in the intermediate process of ESIPT. There appears an energy barrier hopping point on the potential energy curve of M3HF in DMF solvent but does not appear in MeOH solvent.

Organocatalytic decarboxylative alkylation of N-hydroxy-phthalimide esters enabled by pyridine-boryl radicals

The decarboxylative alkylation of N-hydroxyphthalimide (NHPI) based reactive esters with olefins has been achieved via an organocatalytic strategy. Control experiments and density functional theory calculations suggest that these reactions involve a boryl-radical mediated decarboxylation pathway, which is different from the single electron transfer involved in decarboxylative alkylation reactions reported previously. This metal-free decarboxylative alkylation reaction features good functional compatibility, and broad substrate scope illustrated by the transformations of both the alkyl and aryl carboxylic acid derivatives.

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 6624-49-3, help many people in the next few years.Application In Synthesis of Isoquinoline-3-carboxylic acid

Design, synthesis and biological evaluation of a series of novel GPR40 agonists containing nitrogen heterocyclic rings

A novel series of GPR40 agonists is designed by introducing nitrogen-containing heterocyclic ring at the terminal phenyl ring of TAK-875 with the aim of decreasing its lipophilicity. Three different beta-substituted phenylpropionic acids were investigated as the acidic components. A total of 34 compounds have been synthesized, among which, compound 30 exhibited comparable GPR40 agonistic activity in vitro with TAK-875 and relatively lower lipophilicity through calculation (30, EC50 = 1.2 muM, cLogP = 1.3; TAK-875: EC50 = 5.1 muM, cLogP = 3.4). Moreover, compound 30 was able to enhance the insulin secretion of primary islets isolated from normal ICR mice and showed no obvious inhibition against cytochromes P450 in vitro. In vivo, compound 30 exhibited efficacy in oral glucose tolerance test (oGTT) in normal ICR mice.

Diacetyl as a “traceless” visible light photosensitizer in metal-free cross-dehydrogenative coupling reactions

Minisci alkylation is of prime importance for its applicability in functionalizing diverse heteroarenes, which are core structures in many bioactive compounds. In alkyl radical generation processes, precious metal catalysts, high temperatures and excessive oxidants are generally involved, which lead to sustainability and safety concerns. Herein we report a new strategy using diacetyl (2,3-butanedione) as an abundant, visible light-sensitive and “traceless” hydrogen atom abstractor to achieve metal-free cross-dehydrogenative Minisci alkylation under mild conditions. Mechanistic studies supported hydrogen atom transfer (HAT) between an activated C(sp3)-H substrate and diacetyl. Moreover, with the assistance of di-tert-butyl peroxide (DTBP), the scope of the reaction could be extended to strong aliphatic C-H bonds via diacetyl-mediated energy transfer. The robustness of this strategy was demonstrated by functionalizing complex molecules such as quinine, fasudil, nicotine, menthol and alanine derivatives.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C10H9N, you can also check out more blogs about1125-80-0

Three-component coupling reactions of isoquinolines, dimethyl acetylenedicarboxylate and indoles: a facile synthesis of 3-indolyl-1,2-dihydro-2-isoquinolinyl-2-butenedioate

A three-component coupling of isoquinolines, dimethyl acetylenedicarboxylate (DMAD) and indoles is achieved for the first time to produce dimethyl (E)-2-[1-(1H-3-indolyl)-1,2-dihydro-2-isoquinolinyl]-2-butenedioates in excellent yields and with high selectivity. The reaction proceeds smoothly at room temperature without a catalyst. Quinoline, DMAD and indole also undergo smooth coupling to furnish dimethyl (E)-2-[2-(1H-3-indolyl)-1,2-dihydro-1-quinolinyl]-2-butenedioate under similar conditions. This method is very useful to functionalize both indoles and aza-aromatic compounds in a one-pot operation.
