    Novel Route to Enantiopure 2,2'-Diaryl-1,1'-binaphthalenes by Stereoconservative Suzuki Arylation at Positions 2 and 2'
    摘要:
    对手性纯的2,2'-二碘-1,1'-联萘进行银促芳基化反应,可以得到2,2'-二芳基化产物,收率相当可观(高达52%),但会发生明显的拉仑化。采用反向极性方法,使用新型的手性纯1,1'-联萘-2,2'-二基硼酸,通过拆分或立体保持硼化反应制备,经过偶联条件的优化,可以获得模型2,2'-二对甲苯基化产物同样有良好的收率(56%),同时不影响对映体纯度(即立体保持)。这种合成方法被发现是一种方便的方法,特别适用于合成手性纯的2,2'-二芳基-1,1'-联萘,尤其适用于带有电子中性和电子亏缺的芳基团。观察到硼酸在反应条件下通过氢去硼反应分解,与反应性较差的电子富集芳基碘发生反应时,主要产物是2-芳基-1,1'-联萘。

  • Suzuki Coupling of Chiral 1,1′-Binaphthyl Systems − New Synthetic Routes to Functionalize the 2- and 2,2′-Positions

    2′-arylated 1,1-binaphthyls can be synthesized. Selective monoarylation of 3, 4 and 5 can be performed. Subsequent and stepwise arylation offers general access to unsymmetrically substituted binaphthyls. Moreover, interesting atropisomeric complex molecules, such as 4,4′-bis[2-(1,1-binaphthyl)]-1,1′-biphenyl (18a), are accessible. Compounds of type 18, which can be obtained by twofold Pd-catalyzed coupling

    1′-binaphthyl-2,2′-diboronic acid (by resolution) is reported. Optimization of the cross-coupling conditions was found to be crucial to achieve good yields in Suzuki arylation in approaches from both 2,2′-diiodide or 2,2′-diboronic acid (52–56%, with model p-tolyl reagents). Stereochemical results in these reactions were dramatically different: almost complete racemization starting from the 2,2′-diiodide versus

    some chiral P ligands were found to be capable of inducing stereogenic information during this coupling, regardless of the configuration of the starting diiodide. Among those ligands tested in the deracemization approach, binap exhibited the highest level of asymmetric induction, yielding diarylated product in 83 % ee starting from racemic diiodide.

    factors that are investigated and found to affect the stereoselective course of the reaction include the reaction temperature, palladium source, palladium to ligand ratio, and the type of boronic acid derivative. During the chromatographic separation of diarylated products on an achiral silica gel, we observed a rare phenomenon: the diarylated products undergo self-disproportionation of enantiomers, with

  • Study on the electronic effects on stereoconservativity of Suzuki coupling in chiral groove of binaphthyl
    作者:Michal Juríček、Henrich Brath、Peter Kasák、Martin Putala
    DOI:10.1016/j.jorganchem.2007.08.010
    日期:2007.11
    Suzuki diarylation of enantiopure 2,2'-diiodo-1,1'-binaphthyl catalyzed by triphenylphosphane palladium complex is accompanied by almost complete racemization of binaphthyl moiety (7% e.e.). Based on formerly proposed mechanism, secondary oxidative addition of Pd(II) to Pd(IV)-complex, competitive to transmetallation, is expected to be responsible for racemization. In accordance with it, racemization pathway can be suppressed in the favour of stereoconservative route by electronic factors, which control the rate of oxidative addition. Among the electronic factors, decreasing donating ability of the tested phosphane ligands resulted in increase of e.e. of the diarylated product up to 65%, using triindol-l-ylphosphane. However, this factor slows down also the rate of the primary oxidative addition that lowers the yield of the diarylated product. Further decrease in donating ability of the ligand makes palladium complex almost inactive in this cross-coupling reaction. Effect of the leaving group of binaphthyl 2,2'-dielectrophile (as a matter of the reactivity of C-X bond towards oxidative addition) was found to be even more dramatic: almost stereoconservative route in case of 2,2'-dibromo-1,1'binaphthyl (95% e.e.), but no reaction in case of corresponding ditriflate.
