  Catalytic asymmetric addition of aldehydes using organolithium reagents in the presence of commercial available chiral diol ligands

  摘要：

  An efficient method for the catalytic asymmetric additions to aldehydes using organolithium reagents and titanium(IV) isopropoxide in the presence of commercially available and relatively inexpensive diol ligands, such as (S)-BINOL or D-TADDOL has been developed. Good to excellent yields (up to 92%) and enantioselectivities (up to 94%) of the corresponding secondary alcohol products can be obtained following a simple procedure at relatively mild reaction temperatures.

  A highly enantioselective dialkylzinc (R22Zn) addition to a series of aromatic, aliphatic, and heteroaromatic aldehydes (5) was developed based on conjugate Lewis acid−Lewis base catalysis. Bifunctional BINOL ligands bearing phosphine oxides [P(O)R2] (7), phosphonates [P(O)(OR)2] (8 and 9), or phosphoramides [P(O)(NR2)2] (10) at the 3,3‘-positions were prepared by using a phospho-Fries rearrangement

  基于共轭路易斯酸-路易斯碱催化，开发了对一系列芳族，脂族和杂芳族醛（5）的高对映选择性二烷基锌（R 2 2 Zn）。带有氧化膦[P（O）R 2 ]（7），膦酸酯[P（O）（OR）2 ]（8和9）或磷酰胺[P（O）（NR 2）2 ]（10的双功能BINOL配体）通过使用磷酸化-弗里斯重排作为关键步骤来制备3,3'-位。NaphO-Zn（II）-R 2的配位中心以路易斯酸为底物上的羰基，并在3,3'-二磷酰基-BINOL-Zn（II）中以磷酰基（PO）为路易斯碱活化R 2 2 Zn（II）催化剂可以以高对映选择性（高达> 99％ee）促进碳-碳键的形成。通过X射线分析游离配体（7）和四核Zn（II）团簇（21）进行了机理研究，对Zn（II）配合物进行31 P NMR实验，在配体之间没有非线性效应（7））和苯甲醛的Et加合物，以及与某些手性或非手性Zn（II）配合物的化学计量反应，提出了一种包含单体活性中间体的过渡态组装体。

  Highly enantioselective dialkylzinc addition to a series of aldehydes was developed based on chiral Zn(II)-BINOLate catalysts bearing phosphonates [P(=O)(OR) 2 ] and phosphoramides [P(=O)(NMe 2 ) 2 ] at the 3,3'-positions. The reactions proceeded smoothly and showed reductions in the amounts of both catalysts and dialkylzinc reagents to be loaded.

  the resulting mixed titanium reagents undergo addition to aldehydes with high enantioselectivities (typically >90% ee) and high yields. The method is applicable to various combination of aldehydes (R 1 CHO; R 1 = aryl, heteroaryl, 1-alkenyl, and alkyl) and Grignard reagents (R 2 MgX; R 2 = primary alkyl and aryl). Thus, a variety of enantiomerically enriched secondary alcohols (R 1 CH*(OH)R 2 ) can

  我们开发了一种有效且实用的方法，通过使用格氏试剂与四异丙醇钛的组合，对醛进行催化对映选择性烷基化和芳基化。格氏试剂和四异丙醇钛以约 1 的摩尔比混合。1:2。在由 BINOL 配体 4a 和 4b 以及四异丙醇钛原位形成的催化剂（2-4 mol%）存在下，所得混合钛试剂以高对映选择性（通常 >90% ee）和高产量。该方法适用于醛（R 1 CHO；R 1 = 芳基、杂芳基、1-烯基和烷基）和格氏试剂（R 2 MgX；R 2 = 伯烷基和芳基）的各种组合。因此，可以制备多种对映体富集的仲醇(R 1 CH*(OH)R 2 )。也已经证明可以使用官能化的芳基格氏试剂来生成高度官能化的二芳基甲醇。该方法的制备效用已通过以下事实表明：反应操作简单，可以毫无困难地在 10 毫摩尔规模上进行，并且配体可以很容易地回收。
