Selective tandem oxidative C-H olefination-azaMichael/aza-Wacker reaction of N-arylbenzamides is achieved by fine-tuning between base and additive to access valuable 3-oxoisoindolinyls and 3-oxoisoindolinylidenes, respectively. Careful optimization and control experiments provides a guiding principle in the design of a proposed catalytic cycle. The copper-iminium complex acting as a precursor for the binding of Ru catalyst was isolated and confirmed by X-ray diffraction. The versatility of this catalytic system has been demonstrated by the synthesis of biologically relevant molecules.

A novel strategy for the recognition of anions in water using charge-neutral a-hole halogen and chalcogen bonding acyclic hosts is demonstrated for the first time. Exploiting the intrinsic hydrophobicity of halogen and chalcogen bond donor atoms integrated into a foldamer structural molecular framework containing hydrophilic functionalities, a series of water-soluble receptors was constructed for an anion recognition investigation. Isothermal titration calorimetry (ITC) binding studies with a range of anions revealed the receptors to display very strong and selective binding of large, wealdy hydrated anions such as I- and ReO4-. This is achieved through the formation of 2:1 host-guest stoichiometric complex assemblies, resulting in an encapsulated anion stabilized by cooperative, multidentate, convergent a-hole donors, as shown by molecular dynamics simulations carried out in water. Importantly, the combination of multiple sigma-hole-anion interactions and hydrophobic collapse results in I- affinities in water that exceed all known a-hole receptors, including cationic systems (beta(2) up to 1.68 X 10(11) M-2). Furthermore, the anion binding affinities and selectivity trends of the first example of an all-chalcogen bonding anion receptor in pure water are compared with halogen bonding and hydrogen bonding receptor analogues. These results further advance and establish halogen and chalcogen bond donor functions as new tools for overcoming the challenging goal of anion recognition in pure water.

A new, modified total synthesis of (-)-cleistenolide (1) and sixteen new analogues or derivatives was achieved starting from commercially available 1,2-O-isopropylidene-alpha-D-glucofuranose. The synthesis of 1 proceeds in six steps and 67% overall yield, using single-carbon atom degradation of a protected chiral precursor, (Z)-selective Wittig olefination, and acid catalyzed delta-lactonization. A new Lewis acid promoted procedure for one-pot O-debenzylation/O-acylation has been developed to complete the synthesis of natural product 1 and selected analogues. The synthesized compounds were tested in vitro to evaluate their cytotoxicity against K562, HL-60, Jurkat, Raji, MCF-7, MDA-MB 231, HeLa, A549, and MRC-5 cell lines. All (-)-cleistenolide analogues exhibited significantly higher cytotoxicity than lead 1 against the majority of cell lines tested. Most of the synthesized compounds are more active than doxorubicin on at least one malignant cell line, but were almost completely inactive against normal MRC-5 cells. The structural features of the tested compounds responsible for their antiproliferative activity have been identified by preliminary SAR analysis. (C) 2020 Elsevier Masson SAS. All rights reserved.

Picolinamide group assisted sp(3) C-H bond oxidation of methylene groups to the corresponding carbonyl compounds has been achieved by using simple bottle ferrocene as catalyst and Cu(OAc)(2) or tert-butyl peroxybenzoate (TBPB) as oxidant under mild conditions. This method is applicable for picolinamide bound organic as well as organometallic compounds with yields in the range of 46-82%. Control experiments and mechanistic studies indicate that a radical mechanism is responsible for these oxidative transformations in which ferrocene acts as a catalyst.

Previously we have reported that 25-OCH3-PPD could suppress the reproduction of cancer cells and cause apoptosis without obvious toxicity. Herein, we aimed to enhance its bioactivity by introducing aromatic groups to its dammarane-type skeleton. These synthesized derivatives were tested for their inhibitory activities against five cancer cell lines. Of them, compounds 3a, 14a and 18a had the strongest antiproliferative activities against tumor cells (IC50 < 15 mu M, 5-fold to 10-fold increases than 25-OCH3-PPD). Especially compound 14a displayed the most potent activity against DU145, MCF-7 and HepG2 cells (IC50 = 6.7 +/- 0.8, 4.3 +/- 0.8 and 5.8 +/- 0.6 mu M, respectively). Structure-activity relationships demonstrated that having aromatic ester at the C3 position could improve the bioactivity. The data provided new insights into exploring novel antiproliferative lead compounds.

Ortho-alkylated and ortho-acylated pyridines have been conveniently synthesized from pyridine N-oxides and alkynes under visible-light-mediation in a metal-free manner. The alkynes served as both alkylating and acylating agents via switching between anaerobic and aerobic conditions. The overall strategy accommodates a broad scope of substituted pyridine N-oxides and alkynes, with excellent regioselectivity in a number of cases.

A library of 1,2,4-oxadiazole functionalized quinoline derivatives (13a-j) were synthesized and their structures were confirmed by H-1 NMR, (CNMR)-C-13 and Mass Spectral analysis. Further, these compounds were evaluated for their anticancer activity against four human cancer cell lines, namely MCF-7 (breast), A549 (lung), DU-145 (prostate) and MDA MB-231 (breast) using Etoposide as the positive control. Most of these derivatives exhibited more potent activity towards the four cancer cell lines compared to Etoposide. Amongst all the compounds tested, compounds 13b, 13c, 13h, 13i and 13j exhibited promising activity. Further of these compounds 13b, 13i and 13j exhibited excellent activity, when compared with Etoposide.

A desirable alternative to organic solvents, very cheap, non-toxic and biodegradable deep eutectic solvent (DES) based on choline chloride and urea was introduced for 2,4,6-trichloro triazine mediated amide bond formation between carboxylic acids and amines at room temperature. Sub-stoichiometric amount of TCT was used as a cheap and readily available C-O activating reagent. Various derivatives of amines were coupled with carboxylic acids, via triacylated triazine intermediate, resulting the reaction of acids with TCT, and the corresponding amides were obtained in moderate to good yields.
