  An expedient synthesis of enantioenriched substituted (benzofuran-yl)-aryl and heteroaryl carbinols, is described. A key feature of this protocol is synthesis of functionally varied benzofuran scaffolds via a Rap–Stoermer reaction/catalytic asymmetric transfer hydrogenation (ATH) using substituted salicylaldehyde and α-haloaryl, heteroaryl ketones.

  A novel intramolecular oxidative coupling reaction has been established to prepare benzofuran derivatives via direct C(sp²)–H functionalization for the formation of C–O bonds. This transformation is mediated by I₂/TBHP/NaN₃ under metal-free conditions and a catalytic amount of NaN₃ plays a crucial role in the reaction.

  已建立一种新型分子内氧化偶联反应，用于通过直接C(sp²)–H官能化形成C–O键制备苯并呋喃衍生物。此转化在无金属条件下由I₂/TBHP/NaN₃介导，而催化量的NaN₃在反应中起着关键作用。

  Variable benzo[b]furan derivatives having (E)- and (Z)-2-alkylcarbamoyl-1-methylvinyl groups at the 2-, 4- and 5-positions and a carboxylpropoxy or (1-phenyl)ethoxy group at the 7-position were prepared to find novel and selective leukotriene B4 (LTB4) receptor antagonists. (E)-2-(2-Diethylcarbamoyl-1-methylvinyl)-7-(1-phenylethoxy)benzo[b]furan (4v) showed selective inhibition to the human BLT2 receptor (hBLT2). On the other hand, (E)-2-acetyl-4-(2-diethylcarbamoyl-1-methylvinyl)-7-(1-phenylethoxy)benzo[b]furan (7v) inhibited both human BLT1 receptor (hBLT1) and hBLT2. The (E)-2-(2-diethylcarbamoyl-1-methylvinyl) group lay on approximately the same plane as the benzo[b]furan ring, whereas the (E)-4-(2-diethylcarbamoyl-1-methylvinyl) group had the torsion angle (45.7°) from the benzo[b]furan ring plane. However, the (Z)-(2-alkylcarbamoyl-1-methylvinyl)benzo[b]furans were inactive. The inhibitory activity depended on the conformation of the 2-diethylcarbamoyl-1-methylvinyl group.

  合成了变种的苯并[b]呋喃衍生物，这些衍生物在2、4和5位含有(E)-和(Z)-2-烷基氨基甲酰基-1-甲基乙烯基基团，而在7位则含有羧丙氧基或(1-苯基)乙氧基基团，以寻找新型的选择性白三烯B4（LTB4）受体拮抗剂。(E)-2-(2-二乙基氨基甲酰基-1-甲基乙烯基)-7-(1-苯乙氧基)苯并[b]呋喃(4v)对人类BLT2受体(hBLT2)表现出选择性抑制作用。另一方面，(E)-2-乙酰基-4-(2-二乙基氨基甲酰基-1-甲基乙烯基)-7-(1-苯乙氧基)苯并[b]呋喃(7v)则同时抑制人类BLT1受体(hBLT1)和hBLT2。(E)-2-(2-二乙基氨基甲酰基-1-甲基乙烯基)基团大致位于苯并[b]呋喃环的同一平面上，而(E)-4-(2-二乙基氨基甲酰基-1-甲基乙烯基)基团与苯并[b]呋喃环平面之间的扭转角度为45.7°。然而，(Z)-(2-烷基氨基甲酰基-1-甲基乙烯基)苯并[b]呋喃表现出不活性。抑制活性取决于2-二乙基氨基甲酰基-1-甲基乙烯基基团的构象。
• Ruthenium(II)-Catalyzed C3 Arylation of 2-Aroylbenzofurans with Arylboronic Acids/Aryltrifluoroborates via Carbonyl-Directed C–H Bond Activation

  日期：2015.11.20

  The Ru(II)-catalyzed carbonyl-directed C–H activation with (hetero)arylboron reagents has been executed for the synthesis of 2-aroyl-3-(hetero)arylbenzofurans. A hypothesis founded upon the involvement of an active carbonatoruthenium(II) complex for a coordinative insertion and the aerobic oxidation of the in situ generated Ru(0) to Ru(II), to continue the catalytic cycle, has been extended.

  具有（杂）芳基硼试剂的Ru（II）催化的羰基定向C–H活化已被用于合成2-芳基-3-（杂）芳基苯并呋喃。假说的建立是基于活性碳酸化铀（II）配合物的参与以进行配位插入以及原位生成的Ru（0）到Ru（II）的需氧氧化，以继续催化循环，这一假设得到了扩展。
