Olefin aminations are important synthetic technologies for the construction of aliphatic C-N bonds. Here we report a catalytic protocol for olefin hydroamidation that proceeds through transient amidyl radical intermediates that are formed via proton-coupled electron transfer (PCET) activation of the strong N-H bonds in N-alkyl amides by an excited-state iridium photocatalyst and a dialkyl phosphate base. This method exhibits a broad substrate scope, high functional group tolerance, and amenability to use in cascade polycyclization reactions. The feasibility of this PCET protocol in enabling the intermolecular anti-Markovnikov hydroamidation reactions of unactivated olefins is also demonstrated.

Two series of [1,2,4]triazolo[4,3-a]pyrazine derivatives bearing 4-oxo-pyridazinone moieties (compounds 21a-l and 22a-l) were designed and their IC50 values were evaluated against three cancer cell lines (A549, MCF-7 and HeLa) and c-Met kinase. Among them, the compound with most potential, 22i, exhibited excellent anti-tumor activity against A549, MCF-7 and HeLa cancer cell lines with IC50 values of 0.83 +/- 0.07 mu M, 0.15 +/- 0.08 mu M and 2.85 +/- 0.74 mu M, respectively, and it also possessed superior c-Met kinase inhibition ability at the nanomolar level (IC50 = 48 nM). Moreover, dose-dependent experiments, AO fluorescence staining, cell cycle assay, Annexin V-FITC/PI staining and docking studies were carried out in this study. The results demonstrated that compound 22i could be a potential c-Met kinase inhibitor.

A concise and straightforward total synthetic approach towards lycorine-type alkaloid (-)-gamma-lycorane has been achieved in 7 steps. The key feature of the route is the employment of a palladium-catalyzed aromatic C-H alkylation of unactivated secondary alkyl iodide. The synthetic protocols also involve a palladium-catalyzed deracemization of allylic carbonate, a Johnson-Claisen rearrangement and an iodocyclization. (C) 2020 Elsevier Ltd. All rights reserved.

The catalytic asymmetric epoxidation of alpha,beta-unsaturated ketones by tert-butylhydroperoxide (TBHP) has been well established using rare-earth metal amides RE[N(SiMe3)(2)](3) (RE = La(1), Nd(2), Sm(3), Y(4), Yb(5)) with chiral TADDOL ligands. It was found that the combination of Yb[N(SiMe3)(2)](3) and chiral TADDOL ligand H2L2 ((4S,5S)-2,2-dimethyl-alpha,alpha,alpha ‘,alpha ‘-tetra-3,5-bis(trifluormethylphenyl)-1,3-dioxolane-4,5-dimethanol) in a 1 : 1 molar ratio was the optimal choice, which provided the desired epoxides in excellent yields (89-99%) and good to high enantioselectivities (57-94% ee), using DBU as an additive. Various substrates were proved to have functional group tolerance. In addition, gram-level experiments and derivatization experiments were also studied.

A new methodology for the synthesis of alpha-diketones was reported via a one-pot cascade process from aldehydes and ketones catalyzed by a bifunctional iron nanocomposite using H2O2 as a green oxidant in water. The one-pot strategy showed excellent catalytic stability, comprehensive suitability of substrates and important practical utility for directly synthesizing biologically active and medicinally valuable N-heterocycles via an intermittent process.

An efficient and sustainable protocol for the hydration of alkynes has been developed under metal/acid/catalyst/ ligand-free conditions in a water/ethyl lactate mixture. The hydrogen-bond network in the ethyl lactate and water mixture plays a crucial and decisive role in activating the alkynes for hydration to afford the corresponding methyl ketones. This strategy gives the Markovnikov (ketone) addition product selectively over other possible products. The essential role of hydrogen bonding has been confirmed by experimental and theoretical techniques. A probable mechanism has been suggested by various control tests. The efficacy of the method has been further explored for the competent production of value-added alpha,beta-unsaturated carbonyl compounds through the reaction of aldehydes with alkynes as ketonic surrogates. The environmentally benign hydration method takes place under mild conditions, has broad functional-group compatibility, and uses the ethyl lactate/water (1:3) medium as a green alternative in the absence of any hazardous, harmful, or expensive substances.

Bacterial lipopolysaccharides (LPS) are important bio-medical structures, playing a major role in the interaction with human immune systems. Their core regions, containing multiple units ofl-glycero-d-mannoheptoses (l,d-heptose), are highly conserved structurally (withO3 andO7 glycosidic bonds), making them an epitope of high interest for the potential development of new antibiotics and vaccines. Research in this field has always been restricted by the limited availability of the parentl,d-heptose as well as its biochemical epimeric precursord-glycero-d-mannoheptose (d,d-heptose). This problem of availability has recently been solved by us, through a rapid and efficient practical synthesis ofl,d-manno-heptose peracetate demonstrated at scale. Herein we report an optimized, technically simple and versatile synthetic strategy for the differentiation of both thel-glyceroandd-glycero-d-mannoheptose scaffolds. Our approach is based on an orthoester methodology for the differentiation of all three positions of the sugar core using aO6,O7-tetraisopropyl disiloxyl (TIPDS) protecting group for the exocyclic positions. Furthermore, the regioselective opening toward 7-OH acceptors (6O-FTIPDS ethers) differentiates the exocyclic diol which has been demonstrated with a broader set of substrates and for bothmanno-heptoses for the first time.

Chalcones, as a large group of organic compounds, are widely implemented in various types of anticancer therapeutics. These plant metabolites are present in fruits, vegetables, spices, and have anti-tumor, anti-inflammation, immunomodulation, antibacterial and anti-oxidative activities, as well as many other pharmacological and biological effects. The aim of the present study was to investigate cytotoxic effects, type of cell death and mechanism of action of the newly synthesized vanillin based chalcone analogs, (CH1) and (CH2) on human colon cancer HCT-116 and noncancerous (control) MRC-5 cell lines. In order to compare the effects of vanillin based chalcone analogs on investigated cell lines, as reference substances cisplatin (cisPt) and dehydrozingerone (DHZ) were used. Investigation of antitumor effect of chalcone analogs on HCT-116 cells was carried out by three methods MTT assay, flow cytometry and immunofluorescence analysis. The result of our investigation indicated that newly synthesized vanillin based chalcone analogs expressed powerful antitumor effect on cancer cells (HCT-116 cell line), while their effect on healthy cells (MRC-5 cell line) was not statistically significant. Vanillin based chalcone analogs caused overexpression and activation of mitochondrial Bax protein and caspase-3 in HCT-116 cells, indicating that their mechanism of antitumor action was mediated through activation of the inner apoptotic pathway. These results indicate possible usefulness of CH1 and CH2 in antitumor therapy whether through its direct cytotoxic effect or as adjuvant therapy. Our results indicate possible usefulness of CH1 and CH2 vanillin based chalcone analogs in antitumor therapy.
