  Regioselectively Nucleus and/or Side-Chain Fluorinated 2-(Phenanthryl)propionic Acids by an Effective Combination of Radical and Organometallic Chemistry

  摘要：

  Regioselectively nucleus and/or side-chain fluorinated 2-(phenanthr-1-yl)- and 2-(phenanthr-2-yl)-propionic acids 1-5 were prepared using phenanthren-1(2H)-ones 6a-c as key intermediates. Thus. ethyl 2-(fluorophenanthryl)propionates 11 were obtained in good yields by Reformatsky reaction of 6a-c with ethyl 2-bromopropionate followed by dehydratation and DDQ-promoted aromatization of the resulting beta-hydroxyesters. Side-chain alkyl 2-hydroxy-2-(phenanthr-1-yl)propionates 14 were obtained by bromine/lithium permutation of dihydrophenanthryl bromides 12a-c with butyllithium followed by quenching of the lithiated intermediates with methyl pyruvate or ethyl 3,3,3-trifluoropyruvate and subsequent DDQ-promoted aromatization. The alkyl 2-hydroxy-2-(phenanthr-1-yl)propionates 25 were prepared by reacting 8-bromo-1,3-difluorophenanthrene 24 with butyllithium for 10 seconds at -110degreesC and subsequent addition of the suitable pyruvate to the lithiated intermediates. Alkyl 2-hydroxy-2-(phenanthr-2-yl)propionates 26 and 29 were suitably obtained by site-selective metalation of 1,3-difluorophenanthrene 28 and the bromophenanthrene 24: respectively, with LDA followed by quenching of the metalated intermediates with the Suitable alkyl pyruvate. Fluorination of the above alpha-hydroxypropionates with DAST, followed by the alkaline hydrolysis, allowed the expected 2-(phenanthryl)propionic acids 1-5 to be obtained in satisfactory overall yields.

  直接形成源自氰化亚铜溴化锂络合物的官能化和烯丙基有机铜试剂

  摘要：

  生产了一种新型的高反应性零价铜，它在低温下很容易与官能化有机卤化物反应，形成相应的官能化有机铜试剂。这些有机铜试剂与酰氯交叉偶联并以高产率进行共轭加成，以提供高度官能化的酮。由于避免了膦的使用，这些化合物的分离得到了极大的简化。重要的是，这种活性铜允许从烯丙基氯和乙酸酯直接形成烯丙基有机铜物种

  mediated by hypervalent iodine reagents. The reaction proceeds via a reductive iodonium Claisen rearrangement of in situ β-pyridinium silyl enol ethers. The aryl groups are derived from ArI(O2CCF3)2 reagents, which are readily accessed from the parent iodoarenes. It is tolerant of a wide range of substitution patterns and the incorporated arenes maintain the valuable iodine functional handle. Mechanistic

  α,β-不饱和酮的 α 芳基化构成了强大的合成转化。它最常见的是通过α-卤代烯酮的交叉偶联来实现，但是这种逐步策略需要预官能化的底物和昂贵的催化剂。直接烯酮 CH α-芳基化将提供原子和步骤经济的替代方案，但此类报道很少。在此，我们报告了由高价碘试剂介导的烯酮的无金属直接 CH 芳基化。该反应通过原位 β-吡啶鎓甲硅烷基烯醇醚的还原碘鎓克莱森重排进行。芳基衍生自 ArI(O2CCF3)2 试剂，很容易从母体碘代芳烃中获得。它可以容忍广泛的取代模式，并且掺入的芳烃保持了宝贵的碘功能手柄。

  An alternative method to copper-catalyzed conjugate addition followed by enolate silylation for the synthesis of β-disubstituted silyl enol ether products (R(1)(R(2))HCCH═C(OSiR(4)(3))R(3)) is presented. This method uses haloarenes instead of nucleophilic aryl reagents. Nickel ligated to either neocuproine or bipyridine couples an α,β-unsaturated ketone or aldehyde (R(2)HC═CHC(O)R(3)) with an organic

  The conjugate addition of Grignard reagents RMgX to α,β-unsaturated ketones and esters is effectively catalyzed by soluble copper ate-complexes of the type CuX3Li2, e.g. CuI · 2LiCl. In the presence of Me3SiCl the corresponding ketone enolsilanes are formed in high yield and selectivity. Diasteroselectivity in the case of chiral ketones is similar to that observed by using stoichiometric amounts of

  格氏试剂RMgX向α，β-不饱和酮和酯的共轭加成可通过CuX 3 Li 2类型的可溶性铜酸酯络合物（例如CuI·2LiCl ）有效地催化。在Me 3 SiCl存在下，可以高产率和高选择性形成相应的酮烯醇硅烷。在手性酮的情况下，非对映选择性类似于通过使用化学计量的铜酸盐R 2 CuLi所观察到的非对映选择性。因此，CuX 3 Li 2催化的格氏试剂的1，4-加成可能是工业上可行的方法。

  Mn(III)-mediated formal [3+3]-annulation has been developed using readily available vinyl azides and cyclopropanols with a wide range of substituents. Vinyl azides were successfully applied as a three-atom unit including one nitrogen to prepare pyridines and δ-lactams by the reactions with monocyclic cyclopropanols as well as to construct 2-azabicyclo[3.3.1] and 2-azabicyclo[4.3.1] frameworks with

  Mn(III) 介导的正式[3+3]-环化已经使用容易获得的乙烯基叠氮化物和具有广泛取代基的环丙醇开发。乙烯基叠氮化物作为一个含一个氮的三原子单元，通过与单环环丙醇反应制备吡啶和δ-内酰胺，以及构建2-氮杂双环[3.3.1]和2-氮杂双环[4.3.1]骨架，成功应用与双环环丙醇、双环[3.1.0]己-1-醇和双环[4.1.0]庚-1-醇。这些反应是通过 β-羰基自由基的自由基加成引发的，β-羰基自由基是由环丙醇与 Mn(III) 的单电子氧化产生的，与乙烯基叠氮化物产生亚胺基自由基，亚胺基自由基与分子内的羰基环化。此外，将本方法应用于合成四元吲哚生物碱，melinonine-E，

  bromide has been successfully used as an additive instead of hexamethylphosphoric triamide in the O-trimethylsilylation of enolates generated by copper halide-catalyzed reaction of Grignard reagents with a number of α, β-unsaturated carbonyl compounds. Some conjugate additions also proceed satisfactorily in the absence of lithium bromide.
