• Catalytic Enantioselective Addition of Dialkylzinc to <i>N</i>-Diphenylphosphinoylimines. A Practical Synthesis of α-Chiral Amines

  The enantioselective addition of dialkylzinc reagents to N-diphenylphosphinoylimines derived from aryl-, furyl-, and cyclopropylaldehydes is efficiently catalyzed by a copper(II) triflate/(R,R)-MeDUPHOS complex. The yields are high (51-98%), and the enantiomeric excesses vary from 85 to 96%. This route provides a practical route to alpha-chiral amines.

  Commercially available N-benzyl-l-prolinol has shown to be a very efficient catalyst for the enantioselective addition of dialkylzinc reagents to N-(diphenylphosphinoyl)imines. The use of 0.5 equiv of this β-aminoalcohol as a catalyst leads to the expected addition products in good yields and with ees up to 92% in a reaction time of only 4 h at room temperature. This ee is almost equal to the highest

  已经显示，市售的N-苄基-1-脯氨醇是将二烷基锌试剂对映选择性地加成至N-（二苯基膦酰基）亚胺的非常有效的催化剂。使用0.5当量的这种β-氨基醇作为催化剂可得到预期的加成产物，收率良好，在室温下仅4 h的反应时间内，ee最高可达92％。尽管在我们的案例中反应时间要短得多，但该ee几乎等于使用​​0.5当量的氨基醇作为促进剂迄今报道的最高值。催化剂的用量可以减少到0.25当量，而ee则略有下降。已经观察到添加速率和温度对对映选择性的有趣影响。

  Experimental studies on the modification of (1R,2S)-1,2-diphenyl-2-aminoethanol, which is used to promote the alkylation of N-diphenylphosphinoyl benzalimine with diethylzinc, revealed that N-monosubstituted amino alcohols exhibited higher enantioselectivities than their N,N-disubstituted counterparts and imino alcohols. Application of the optimal chiral ligand 3c to activate the reaction of N-diphenylphosphinoyl

  对用于促进N-二苯基膦酰基苯扎明与二乙基锌烷基化的（1R，2S）-1,2-二苯基-2-氨基乙醇的改性实验研究表明，N-单取代氨基醇的对映选择性高于N ，N-二取代对应物和亚氨基醇。最佳手性配体3c的应用可激活N-二苯基膦酰基芳基丙氨酸与二乙基锌和二丁基锌的反应，可产生高达98％ee的出色对映异构体选择性。通过对几种模型反应的过渡结构进行密度泛函计算（B3LYP / 6-31G *），揭示了实验观察到的对映选择性的起源。

  We have shown that Me-DuPHOS monoxide (BozPHOS) is a very effective ligand in the copper-catalyzed addition of dialkylzinc to N-phosphinoylimines providing access to alpha-chiral amines. The new ligand is particularly effective for the addition of the lesser reactive dimethylzinc. The major advantages of this process are high yields, broad substrate scope, and high enantioselectivities with low catalyst

  我们已经证明 Me-DuPHOS 一氧化 (BozPHOS) 在铜催化下将二烷基锌加成到 N-膦亚胺中是一种非常有效的配体，提供了获得 α-手性胺的途径。新配体对于添加反应性较低的二甲基锌特别有效。该方法的主要优点是收率高、底物范围广、对映选择性高、催化剂负载量低（3 mol%）。
• Enantioselective addition of dialkylzinc reagents to N-(diphenylphosphinoyl)imines catalyzed by β-aminoalcohols with the prolinol skeleton

  Several beta-aminoalcohols with the prolinol framework are shown to be very efficient catalysts for the enantioselective addition of dialkylzinc reagents to N-(diphenylphosphinoyl)imines. The use of 0.5 equiv of the catalyst leads to the expected addition products in good yields and with ee up to 94% in a reaction time of only 4 It at room temperature. This ee is the highest value reported so far using 0.5 equiv of an aminoalcohol as a promoter. High enantioselectivities are obtained in the addition of dialkylzincs to both aromatic and aliphatic imines. The amount of the catalyst can be reduced to 0.25 equiv with a slight decrease in the ee. A very interesting effect of the addition rate and temperature on the enantioselectivity was also observed. (c) 2007 Elsevier Ltd. All rights reserved.
