• Cobalt-Catalyzed Cross-Coupling Reactions of Heterocyclic Chlorides with Arylmagnesium Halides and of Polyfunctionalized Arylcopper Reagents with Aryl Bromides, Chlorides, Fluorides and Tosylates

  A range of aromatic organocopper or organomagnesium compounds undergo smooth cross-coupling reactions with aryl bromides, chlorides, fluorides and tosylates, leading to polyfunctionalized aromatics or heterocycles in the presence of cobalt salts (5-7.5 mol%) as catalysts. Very mild reaction conditions are needed and, in the case of cross-coupling with organocopper compounds, Bu4NI (1 equiv) and 4-fluorostyrene (20 mol%) are essential as promoters for successful couplings.

  一系列芳香族有机铜或有机镁化合物与芳基溴、氯、氟及托烯磺酸酯进行平滑的交叉偶联反应，在钴盐（5-7.5 mol%）作为催化剂的情况下，产生多功能化的芳香族化合物或杂环化合物。反应条件非常温和，且在与有机铜化合物交叉偶联的情况下，四丁基氮化铵（1当量）和4-氟苯乙烯（20 mol%）是成功偶联所必需的促进剂。

  Oxidative heterocoupling between two Grignard reagents RMgX and R′MgX is made possible by manganese catalysis with O2 as an oxidant. This procedure, development of which was based on mechanistic analysis of the corresponding homocoupling reaction, can be steered towards the heterocoupling product at the expense of the homocoupling products by judicious choice of the R and R′ groups (see examples).

  通过以O 2为氧化剂的锰催化，可以实现两种格氏试剂RMgX和R'MgX之间的氧化杂化。该方法的开发是基于对相应的均偶联反应的机理分析，可以通过明智地选择R和R'基团，以牺牲均偶联产物为导向，转向异偶联产物（参见示例）。

  Palladium-catalyzed cross-coupling reactions of functionalized bromofurans with triarylbismuths have been described for the atom-economic synthesis of functionalized arylfuran systems. The coupling reactions using triarylbismuths with various 2-bromofurans and 2,5-dibromofuran underwent smoothly to afford the corresponding 2-arylfurans and 2,5-diarylfurans in high yields in a short reaction time (one

  can be arylated at the α-position in moderate to good yields. Mechanistic studies demonstrate that the reaction proceeds via a CMD pathway, with C–H bond activation as the rate-determining step. Furthermore, the scalability and applicability in the synthesis of a drug molecule exemplify the utility of this protocol.

• Triflic Acid-Catalyzed Cycloisomerization Reactions of Donor–Acceptor Cyclopropanes: Access to Alkyl 5-Arylfuran-2-carboxylates

  日期：2016.6.3

  A direct synthetic strategy starting from alkyl 1-alkoxy-2-aroylcyclopropanecarboxylates was developed for the construction of alkyl 5-arylfuran-2-carboxylates. These donor acceptor cyclopropanes smoothly undergo a simple ring opening reaction or/and cycloisomerization reaction in the presence of acid at room temperature;, which greatly depends on the properties of the acid used in the experiment, Alkyl 5-arylfuran-2-carboxylates were afforded in high yields in triflic acid, whereas alkyl 2,5-dioxo-5-phenylpentanoate became the major product in other protic acids and Lewis acids.
