Although methyl transfer reactions are important in both chemical and biological systems, there is a need for thermodynamic parameters related to methyl affinity and O-CH3 bond dissociation enthalpies (BDEs) relevant to a full understanding of the mechanisms of methyl transfer reactions. As a prelude to the construction of a database of O-CH3 BDEs, the present work examines the reliability of a series of theoretical methods for the prediction of O-CH3 BDEs using a set of 25 compounds that included both aromatic and non-aromatic molecules. The BDEs calculated by density functional theory (DFT) with traditional exchange-correlation functions exhibited much larger errors than those obtained by either the M06-2X or G4 methods. For the non-aromatic compounds, M06-2X/def2-TZVP performed slightly better than G4, but G4 was more accurate for the aromatic molecules. As a result, we recommend G4 as the preferred method for the theoretical estimation of O-CH3 bond dissociation enthalpies, although M06-2X may be a good alternative for large complex molecules when the use of G4 is impractical.

An article Synthesis and Antiproliferative Activity of Natural and Non-Natural Polymethoxychalcones and Polymethoxyflavones WOS:000461554200004 published article about MANNICH BASE DERIVATIVES; ANTICANCER; CHALCONES in [Vongdeth, Kingsadingthongkham; Han, Peipei; Li, Wei; Wang, Qiu-An] Hunan Univ, Coll Chem & Chem Engn, Changsha 410082, Hunan, Peoples R China; [Vongdeth, Kingsadingthongkham] Natl Univ Laos, Fac Nat Sci, Dept Chem, Dong Dok Campus,North 13rd,POB 7322, Vientiane Capital, Laos in 2019, Cited 23.

Two series of polymethoxychalcones and polymethoxyflavones, including the natural products 2-hydroxy-3,4,5,4,6-pentamethoxychalcone (8c), 5,6,7,8,3,4,5-heptamethoxyflavone (6), 5,7,3,4,5-pentamethoxyflavone (9c), 3-hydroxy-5,6,7,8,3,4,5-heptamethoxyflavone (7), and 3-hydroxy-5,7,3,4,5-pentamethoxyflavone (10), were synthesized. The antiproliferative activity in vitro was evaluated against a panel of three human cancer cell lines (HeLa, HCC1954, and SK-OV-3) by the cell counting kit-8 (CCK-8) assay. The results showed that most of the synthetic compounds exhibited moderate to potent antiproliferative activities. Some compounds displayed equal or higher potential than the positive control drug cisplatin. In particular, compounds 4c, 4e, 8a, and 9a possess IC50 values equal to or below 10 M and are worthy of further investigation.

A copper/silver co-catalyzed cross-dehydrogenative coupling reaction is developed to achieve exclusively remote C5-H coupling of 8-aminoquinoline amides with the methylenic sp (3) C-H bond of 1,3-dicarbonyl compounds. This protocol provides a highly regioselective synthetic route for the functionalization of 8-aminoquinoline amides at C5 under mild conditions. Preliminary experiments reveal that radicals may be involved in this catalytic transformation.

We synthesized two kinds of monocarbamothioates TZO(R) containing a thiazolidin-2-one (TZO) skeleton and TZD(R) containing a thiazolidine-2,4-dione (TZD) skeleton. In the reaction of TZO(R) and phenoxypropyrenesulfide (PPS) using tetrabutylammonium chloride (TBAC) as a catalyst in 1-methyl-2-pyrrolidinone at 60 degrees C, anionic ring-opening polymerization of PPS proceeded to give the corresponding linear polysulfides, polyPPS, with M-n = 75 860-206 700 (M-w/M-n = 1.54-1.73) in high yield. In contrast, in the reaction of TZD(R) and PPS, the continuous insertion reaction of PPS into TZD(R), i.e., living ring-expansion polymerization, occurred to afford cyclic polysulfides TZD(R)-c-poly(PPS)(n) with M-n = 1870-33 420 (M-w/M-n = 1.07-1.26) in high yield. The ring size could be controlled by the feed ratio of TZD(R)/PPS in the range of 1/5-1/100.

Nonsteroidal anti-inflammatory drugs (NSAIDs) cause peptic lesions in the gastrointestinal mucosa by inhibiting the cyclooxygenase-1 (COX-1) enzyme. Selective COX-2 inhibition causes decreased side effects over current NSAIDs. Therefore, the studies about selective inhibition of COX-2 enzyme are very important for new drug development. The design, synthesis and biological activity evaluation of novel derivatives bearing thiazolylhydrazine-methyl sulfonyl moiety as selective COX-2 inhibitors were aimed in this paper. The structures of synthesized compounds were assigned using different spectroscopic techniques such as H-1 NMR, C-13 NMR and HRMS. In addition, the estimation of ADME parameters for all compounds was carried out using in silico process. The evaluation of in vitro COX-1/COX-2 enzyme inhibition was applied according to the fluorometric method. According to the enzyme inhibition results, synthesized compounds showed the selectivity against COX-2 enzyme inhibition as expected. Compounds 3a, 3e, 3f, 3g, 3i and 3j demonstrated significant COX-2 inhibition potencies. Among them, compound 3a was found to be the most effective derivative with an IC50 value of 0.140 +/- 0.006 mM. Moreover, it was seen that compound 3a displayed a more potent inhibition profile at least 12-fold than nimesulide (IC50 = 1.684 +/- 0.079 mu M), while it showed inhibitory activity at a similar rate of celecoxib (IC50 = 0.132 +/- 0.005 mu M). Molecular modelling studies aided in the understanding of the interaction modes between this compound and COX-2 enzyme. It was found that compound 3a had a significant binding property. In addition, the selectivity of obtained derivatives on COX-2 enzyme could be explained and discussed by molecular docking studies. (C) 2020 Elsevier Masson SAS. All rights reserved.

N-Aryl amides are an important class of compounds in pharmaceutical and agrochemical chemistry. Rapid and low-cost synthesis of N-aryl amides remains in high demand. Herein, we disclose an operationally simple process to access N-aryl amides directly from readily available nitroarenes and carboxylic acids as coupling substrates. This method involves the in situ activation of carboxylic acids to acyloxyphosphonium salt for one-pot amidation, without the need for isolation of the corresponding synthetic intermediates. Furthermore, the ease of preparation and workup allow the quick and efficient synthesis of a wide range of N-aryl amides, including several amide-based druglike and agrochemical molecules.

The direct reduction of carboxylic acids to aldehydes is a fundamental transformation in organic synthesis. The combination of an air-stable Ni precatalyst, dimethyl dicarbonate as an activator, and silane reductant effects this reduction for a wide variety of substrates, including pharmaceutically relevant structures, in good yields and with no overreduction to alcohols. Moreover, this methodology is scalable, allows access to deuterated aldehydes, and is also compatible with one-pot utilization of the aldehyde products.

The photoredox chloroacylation of alkenes has been developed as a substitute for the Friedel-Crafts acylation of alkenes to beta-chloroketones. The direct generation of acyl radical species from acid chlorides under the photoredox conditions allows the formation of beta-chloroketones without dehydrochlorination with the help of KHCO3. The synthetic utility of the current method is demonstrated in the one-pot synthesis of dihydroisoxazole, dihydropyrazole, and dihydropyrimidine-2-thione in 1 mmol scale.
