  Samarium(II)-Promoted Radical Spirocyclization onto an Aromatic Ring

  摘要：

  Samarium(II)-mediated spirocyclization onto an aromatic ring was achieved by the reaction of methyl 4-(4-oxoalkyl)benzoates with SmI2 in the presence of i-PrOH and HMPA, yielding methyl 1-alkyl-1-hydroxyspiro[4.5]dec-6-ene-8-carboxylates in moderate to high yields. Utilizing this chemistry, spiro[3.5] and -[5.5] systems, and sterically congested spiro[4.5] systems, were easily synthesized. For the successful conversion, appropriate activation of the aromatic ring has proven to be extremely important: while an ester or amide functionality on the aromatic ring can promote the spirocyclization, a sulfonamide substituent causes ortho cyclization.

• Design of an Indolylphosphine Ligand for Reductive Elimination-Demanding Monoarylation of Acetone Using Aryl Chlorides

  elimination-demanding Pd-catalyzed mono-α-arylation of acetone is demonstrated and reported. The catalyst is tolerant of previously proven challenging electron-deficient aryl chlorides and provides excellent product yields with down to 0.1 mol % Pd. Preliminary investigations suggest that the rate-limiting step for the proposed system is the oxidative addition of aryl chlorides, in which it contradicts

  证明并报道了膦配体的合理设计，该膦配体用于还原性消除要求的Pd催化的丙酮单α-芳基化反应。该催化剂可耐受先前证明的具有挑战性的缺乏电子的芳基氯化物，并能以低至0.1 mol％的Pd提供出色的产品收率。初步研究表明，所提出系统的限速步骤是氧化加成芳基氯，在该反应中，它与先前有关丙酮与芳基卤化物的α-芳基化的发现相矛盾。
• An Efficient Palladium-Catalyzed α-Arylation of Acetone Below its Boiling Point

  The monoarylation of acetone is a powerful transformation, but is typically performed at temperatures significantly in excess of its boiling point. Conditions described for performing the reaction at ambient temperatures led to significant dehalogenation when applied to a complex aryl halide. We describe our attempts to overcome both issues in the context of our drug-discovery program.

  丙酮的单芳基化是一种强大的转化，但通常在显着超过其沸点的温度下进行。在环境温度下进行反应所描述的条件在应用于复杂的芳基卤化物时会导致显着的脱卤。我们描述了我们在药物发现计划的背景下克服这两个问题的尝试。

  of aryl halides and activated alkyl halides in DMF in the presence of catalytic amount of NiBr(2)bipy leads to cross-coupling products in good to high yields. The method applies to the synthesis of alpha-aryl ketones, alpha-aryl esters, and allylated compounds from readily available organic halides. Optimization of the process has been obtained by slowly adding the most reactive organic halide (usually

  在催化量的NiBr（2）bipy存在下，在DMF中对芳基卤化物和活化的烷基卤化物的混合物进行电化学还原，可得到高至高收率的交叉偶联产物。该方法适用于由容易获得的有机卤化物合成α-芳基酮，α-芳基酯和烯丙基化的化合物。通过在电解过程中缓慢加入反应性最强的有机卤化物（通常是活化的烷基卤化物），可以实现工艺的优化，这最好是在涉及芳基溴化物的情况下，在70摄氏度下进行。

  α‐Aryl ketones are both structure moieties commonly found in bioactive compounds and versatile synthetic intermediates for the preparation of drug‐like molecules. An operationally simple and scalable protocol has been developed to prepare α‐aryl ketones from readily available aromatic amines and enol acetates (or silyl enol ethers). This metal‐free methodology features the use of salicylic acid as

  α-芳基酮既是生物活性化合物中常见的结构部分，又是制备类药物分子的通用合成中间体。已开发出一种操作简单且可扩展的方案，以从易于获得的芳族胺和烯醇乙酸酯（或甲硅烷基烯醇醚）制备α-芳基酮。这种无金属方法的特点是使用水杨酸作为方便的催化剂，以促进由原位生成的芳基重氮盐形成芳基，而无需进行热或光化学活化。所用的温和反应条件与被各种官能团取代的苯胺相容。一些准备好的α的结构精细化制备了芳基酮以说明其作为构件的有用性。
