  摘要：

  炔丙基芳基醚与二芳基二硒化物的无金属氧化自由基环化/硒基化反应得到了发展。该协议提供了另一种方法，可通过一步形成C-Se键，CC键和C = O键来合成3-有机硒基-2 H-香豆素。而且，宽泛的官能团（例如卤素，醛，酮，氰基和硝基）是可以容忍的。

  A one‐pot synthesis of tetrasubstituted acrylaldehydes via difunctionalization of aryl propynyl ethers has been achieved, which involves a trifluoromethylthiolation process and a radical 1,4‐aryl migration from oxygen to carbon. The reaction shows excellent conversion of aryl propynyl ethers into trifluoromethyl‐containing α,β‐unsaturated aldehydes through a radical pathway.

  A novel series of P-glycoprotein (P-gp)-mediated multidrug resistance (MDR) inhibitors with triazol-N-phenethyl-tetrahydroisoquinoline or triazol-N-ethyl-tetrahydroisoquinoline scaffold were designed and synthesized via click chemistry. Most of the synthesized compounds showed higher reversal activity than verapamil (VRP). Among them, the most potent compound 4 showed a comparable activity with the known potent P-gp inhibitor WK-X-34 with lower cytotoxicity toward K562 cells (IC50 > 100 mu M). Compared with VRP, compound 4 exhibited more potency in increasing drug accumulation in K562/A02 MDR cells. Moreover, compound 4 could significantly reverse MDR in a dose-dependent manner and also persist longer chemo-sensitizing effect than VRP with reversibility. Further mechanism studies revealed that compound 4 could remarkably increase the intracellular accumulation of Adriamycin (ADM) in K562/A02 cells as well as inhibit rhodamine-123 (Rh123) efflux from the cells. These results suggested that compound 4 may represent a promising candidate for developing P-gp-mediated MDR inhibitors. (C) 2016 Elsevier Ltd. All rights reserved.

  A metal‐free oxidative radical cyclization/selenylation of propargylic aryl ethers with diaryl diselenides was developed. This protocol provided an alternative method to synthesize 3‐organoselenyl‐2H‐coumarins via the formation of C−Se bond, C−C bond, and C=O bond in one step. Moreover, a broad range of functional groups (such as halogen, aldehyde, ketone, cyano, and nitro group) were tolerated.
