  highly reactive RMgBr reagents were effectively deactivated by bis[2-(N,N-dimethylamino)ethyl] ether and then were employed in the highly enantioselective addition of Grignard reagents to aldehydes. The reaction was catalyzed by the complex of commercially available (S)-BINOL and Ti(Oi-Pr)4 under mild conditions. Compared with the other observed Grignard reagents, alkyl Grignard reagents showed higher enantioselectivity

  常用的高反应性RMgBr试剂可通过双[2-（N，N-二甲基氨基）乙基]醚有效失活，然后用于格氏试剂对醛的高对映选择性加成反应。在温和条件下，通过可商购的（S）-BINOL和Ti（O i- Pr）4的配合物催化该反应。与其他观察到的格氏试剂相比，烷基格氏试剂表现出更高的对映选择性，并且ee值> 99％。

  The first copper(I)‐catalyzed enantioselective borylation of racemic benzyl chlorides has been realized by a quadrant‐by‐quadrant structure modulation of QuinoxP*‐type bisphosphine ligands. This reaction converts racemic mixtures of secondary benzyl chlorides into the corresponding chiral benzylboronates with high enantioselectivity (up to 92 % ee). The results of mechanistic studies suggest the formation

  of the high reactivity of Grignard reagents, a direct, highly enantioselective Grignard reaction with aldehydes has rarely been disclosed. In this report, Grignard reagents were introduced with bis[2-(N,N′-dimethylamino)ethyl] ether (BDMAEE) to effectively deactivate their reactivity; thus, a highly enantioselective alkylation of aldehydes with Grignard reagents resulted from catalysis by (S)-BINOL-Ti(OiPr)2

  由于格氏试剂的高反应性，很少公开与醛类直接，高度对映选择性的格氏试剂反应。在该报告中，格氏试剂与双[2-（N，N'-二甲基氨基）乙基]醚（BDMAEE）一起引入，以有效地使其活性失活。因此，由（S）-BINOL-Ti（O i Pr）2催化导致格氏试剂对醛的高度对映选择性烷基化。认为BDMAEE螯合了RMgBr的Schlenk平衡的原位生成的盐MgBr 2和RMgBr与Ti（O i Pr）4的重金属化产生的Mg（O i Pr）Br的螯合作用。镁盐可以积极地促进不希望有的背景反应，生成外消旋体。该螯合作用无疑抑制了Mg盐的催化活性，抑制了不需要的背景反应，并且使得能够被（S）-BINOL-Ti（O i Pr）2催化的高对映选择性加成。因此，与以前的研究相比，没有除去Mg盐的副产物，使用了比RMgBr少的Ti（O i Pr）4，并且在该催化不对称反应中避免了极低的温度。各种烷基格氏试剂中的不对称

The same stereochemistry of RTi(O‐i‐Pr)3 addition reactions as the addition reactions of organozinc, organoaluminum, Grignard, or organolithium reagents directly supports the argument of that titanium‐catalyzed addition reactions of aldehydes involve an addition of an organotitanium nucleophile
