  agents designated as N-phenyl 4-(2-oxoimidazolidin-1-yl)benzenesulfonates (PIB–SOs) and phenyl 4-(2-oxoimidazolidin-1-yl)benzenesulfonamides (PIB–SAs). Our previous structure-activity relationship studies (SAR) focused on the aromatic ring B of PIB-SOs and PIB-SAs leaving the impact of the phenylimidazolidin-2-one moiety (ring A) on the binding to the colchicine-binding site (C-BS) poorly studied. Therefore

  我们最近设计并制备了新的有效抗微管剂家族，命名为N4-（2-氧代咪唑啉-1-基）苯磺酸苯酯（PIB-SOs）和4-（2-氧代咪唑啉-1-基）苯磺酰胺（PIB-SAs）。我们之前的结构活性关系研究（SAR）专注于PIB-SO和PIB-SA的芳香环B，而苯基咪唑啉二-2-酮部分（环A）对秋水仙碱结合位点的结合（C -BS）学习得不好。因此，本研究的目的是评估由吡咯烷-2-酮部分取代咪唑烷-2--2-酮（IMZ）的效果。为此，设计，制备了15种新的4-（2-氧杂吡咯烷-1-基）苯磺酸苯基酯（PYB-SO）和15种苯基4-（2-氧杂吡咯烷-1-基）苯磺酸酰胺（PYB-SA）衍生物，化学表征和生物学评估。PYB-SO和PYB-SA在低纳摩尔至低微摩尔范围内显示抗增殖活性（0。在人HT-1080，HT-29，M21和MCF7癌细胞系上分别为0087–8.6μM和0.056–21μM）。而且，它们阻断了G2

  A novel Co/Ni bimetallic nanoparticle supported by nitrogen-doped porous carbon (NPC), Co5/Ni@NPC-700, exhibits high conversion, chemoselectivity, and recyclability in the hydrogenation of 16 different nitro compounds into desired amines with hydrazine hydrate under mild conditions. The synergistic effects of Co/Ni bimetal nanoparticles and the NPC-supported porous honeycomb structure with more accessible

  We report sodium trihydroxyaryl borates as the first robust tetracoordinate organoboron catalysts for reductive functionalization of CO2. These catalysts, easily synthesized from condensing boronic acids with metal hydroxides, activate main group element–hydrogen (E–H) bonds efficiently. In contrast to BX3 type boranes, boronic acids and metal-BAr4 salts, under transition metal-free conditions, sodium

  我们报告三羟基芳基硼酸钠作为第一个坚固的四配位有机硼催化剂，用于CO 2的还原功能化。这些催化剂很容易从硼酸与金属氢氧化物的缩合反应中合成，可以有效地活化主族元素氢键。与BX 3型硼烷，硼酸和金属-BAr 4盐相比，在无过渡金属的条件下，三羟基芳基硼酸钠对各种胺（包括带有官能团的胺）表现出较高的还原性N-甲酰化反应性（106例）例如酯，烯烃，羟基，氰基，硝基，卤素，MeS–，醚基等。催化具有挑战性的吡啶胺的甲酰化反应的性能过高，为使用传统的甲酰化试剂提供了一种有前途的替代方法。机理研究支持将静电相互作用作为Si / B–H活化的关键，从而使碱金属硼酸盐成为用于CO 2加氢硼化，加氢硅烷化和还原甲酰化/甲基化的通用催化剂。

  An enantioselective copper-catalyzed arylation of tertiary carbon-centered radicals, leading to quaternary all-carbon stereocenters, has been developed herein. The tertiary carbon-centered radicals, including both benzylic and nonbenzylic radicals, were produced by the addition of trifluoromethyl radical to α-substituted acrylamides, and subsequently captured by chiral aryl copper(II) species to give

  本文开发了一种对映选择性铜催化的叔碳中心基团芳基化，导致季全碳立体中心。叔碳中心自由基，包括苄基和非苄基自由基，是通过将三氟甲基自由基加成到 α-取代的丙烯酰胺中产生的，随后被手性芳基铜 (II) 物种捕获，以产生具有优异对映选择性的 C-Ar 键。重要的是，与叔碳自由基相邻的酰基酰胺基 (CONHAr) 基团对于不对称自由基偶联至关重要。该反应本身具有底物范围广、官能团相容性好、条件温和等特点。
