The synthesis, electronic structure, and reactivity of a uranium metallacyclopropene were comprehensively studied. Addition of diphenylacetylene (PhC equivalent to CPh) to the uranium phosphinidene metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U=P-2,4,6-tBu(3)C(6)H(2) (1) yields the stable uranium metallacyclopropene, [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U[eta(2)-C2Ph2] (2). Based on density functional theory (DFT) results the 5f orbital contributions to the bonding within the metallacyclopropene U-(eta(2)-C=C) moiety increases significantly compared to the related Th-IV compound [eta(5)-1,2,4-(Me3C)(3)C5H2](2)Th[eta(2)-C2Ph2], which also results in more covalent bonds between the [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U2+ and [eta(2)-C2Ph2](2-) fragments. Although the thorium and uranium complexes are structurally closely related, different reaction patterns are therefore observed. For example, 2 reacts as a masked synthon for the low-valent uranium(II) metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U-II when reacted with Ph2E2 (E=S, Se), alkynes and a variety of hetero-unsaturated molecules such as imines, ketazine, bipy, nitriles, organic azides, and azo derivatives. In contrast, five-membered metallaheterocycles are accessible when 2 is treated with isothiocyanate, aldehydes, and ketones.

Hydroboration of carbonyl compounds is an important transformation in organic chemistry, and a growing interest in catalysis has focused on abundant and nontoxic base metals. Herein we describe an efficient salen manganese catalyst for the hydroboration of a broad range of carbonyl compounds with pinacolborane. The catalytic reactions proceeded rapidly (>99% conversion in <5 min) at room temperature with very low catalyst loadings. High turnover frequency (up to 5700 h(-1)) was observed under these conditions. Several synthetically important functional groups were tolerated, and chemoselective hydroboration of aldehydes over ketones was achieved. The H/D kinetic isotopic effect of borane was determined to be 2.3. The Hammett correlation plot of a series of para-substituted acetophenone substrates, p-X-C6H6COCH3 (X = H, Me, OMe, NO2, Cl, Br, and CF3) yielded a positive slope of rho = +0.99. The crossover products were detected in the competition reaction of catecholborane and deuterated pinacolborane with acetophenone. The findings indicated a potential borane-mediated pathway that could account for the observation of the crossover products. Category: benzodioxans.

A convenient one-pot, three-component, and solvent-free procedure for the preparation of substituted (E)-1-phenyl-3-[2-(piperidin-1-yl)quinolin-3-yl]prop-2-en-1-ones, which has made a significant improvement of previously reported methods, has been developed. The reaction of chloro aldehydes, ketones, and piperidine under microwave irradiation afforded the corresponding piperidine-substituted chalcone derivatives in high yields in shorter reaction times. All the synthesized compounds were characterized by IR and H-1 and C-13 NMR spectroscopy, and mass spectroscopy.

A series of novel chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) were designed, synthesized and their structures were confirmed by H-1 NMR, C-13 NMR and mass spectral data. Further, all derivatives were tested for their anticancer activities against five human cancer cell lines such as MCF-7 (breast cancer), A-549 (lung cancer), Colo-205 (colon cancer), A2780 (ovarian cancer) and DU-145 (prostate cancer) by employing MIT assay. The clinically used drug etoposide was used as standard reference and the anticancer activity was expressed as the IC50 in mu M. Among the ten compounds examined compounds, 10b, 10c, 10d, 10h, and 10i possessed more promising anticancer activity. A molecular docking study implying ATR kinase was carried out to observe the binding mode of chalcone derivatives pyrido[4,3-b]pyrazin-5(6H)-one (10a-j) on the active site of ATR kinase. The most promising compound, 10h showed pi – pi stacking interaction of trimethoxy phenyl and pyridone moiety with the residue Trp850, while the carbonyl (alpha,beta-unsaturated carbonyl) and methoxy functions showed H-bond interaction with the residue Ser773 and Thr856 respectively.

Chemical diversification of type II topoisomerase (Topo II) inhibitors remains indispensable to extend their anti-tumor therapeutic values which are limited by their side effects. Herein, we designed and synthesized a novel series of benzimidazole-chalcone hybrids (BCHs). These BCHs showed good inhibitory effect in the Topo II mediated DNA relaxation assay and anti-proliferative effect in 4 tumor cell lines.4dand4nwere the most potent, with IC(50)values less than 5 mu M, superior to etoposide. Mechanistic studies indicated that the BCHs functioned as non-intercalative Topo II catalytic inhibitors. Moreover,4dand4ndemonstrated versatile properties against tumors, including inhibition on the colony formation and cell migration, and promotion of apoptosis of A549 cells. The structure-activity relationship and molecular docking analysis suggested possible contribution of the chalcone motif to the Topo II inhibitory and anti-proliferative potency. These results indicated that4dand4ncould be promising lead compounds for further anti-tumor drug research.
