    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。

  • The development of an approach toward sterically-hindered chiral 2′-aryl-1,1′-binaphthalenes functionalized at position 2

    Several approaches were examined for the preparation of 1,1'-binaphthalene derivatives bearing sterically demanding ortho-substituted aryl at position 2' which are suitable for further functionalization at position 2. Steric hindrance of ortho-substituted aryl groups was critical for the approach through BINOL monotriflate. Among variations of cross-coupling reactions of 2,2'-dihalo-1,1'-binaphthalenes, Negishi arylation of an enantiopure 2,2'-dibromide was found to be the method of choice for regioselective and stereoconservative preparation of the target 2'-monoarylated precursor. Functionalization of the latter at position 2 was demonstrated by bromine substitution via lithiation followed by the reaction with several electrophiles. (C) 2011 Elsevier Ltd. All rights reserved.
  • Novel Route to Enantiopure 2,2'-Diaryl-1,1'-binaphthalenes by Stereoconservative Suzuki Arylation at Positions 2 and 2'

    The Suzuki arylation of enantiopure 2,2'-diiodo-1,1'-binaphthalene affords the 2,2'-diarylated products in considerable yields (up to 52%), however, significantly racemized. The reversed-polarity approach, using novel enantiopure 1,1'-binaphthalene-2,2'-diyldiboronic acid, prepared either by resolution or by stereoconservative boronation, allowed, after optimization of coupling conditions, to obtain the model 2,2'-ditolylated product in good yield (56%) as well, but in addition, without impairing of enantiomeric purity (i.e. stereoconservatively). The developed synthetic approach was found to be an expedient method for the synthesis of enantiopure 2,2'-diaryl-1,1'-binaphthalenes, especially for those with electron-neutral and electron-deficient poor aryl groups. Observing that the diboronic acid decomposes by hydrodeboronation under the reaction conditions, 2-aryl-1,1'-binaphthalenes were isolated as the main products from the reaction with less reactive electron-rich aryl iodides.
