    新的C 2-对称的双磺酰胺配体的合成及其在炔醛与醛和酮的对映选择性加成中的应用
    摘要:
    新颖的C 2-对称双磺酰胺配体易于通过三个简单步骤制备,并用于炔基锌试剂对醛的对映选择性加成。发现化合物7a是该反应的杰出配体。当使用4mol%的7a的催化剂负载量时,在非常温和的条件下获得了ee值高达97%的高对映选择性。当配体7a的量降低至2mol%时,仍达到高达95%ee的优异对映体控制水平。迄今为止,已开发出最经济的催化剂体系,用于在配体负载和对映选择性方面向芳族醛中添加末端炔烃。此外,配体7a发现与Ti(O - Pr)4组合可以有效地促进炔基锌试剂在非常温和的条件下与未活化的简单酮的加成反应。得到相应的手性叔炔丙醇,其对映体过量最高为81%。

    achieved. So far the most economic catalyst system was developed for the addition of terminal alkynes to aromatic aldehydes in terms of ligand loading and enantioselectivity. Moreover, ligand 7a in combination with Ti(O-i-Pr)4 was found to be effective in promoting the addition reaction of an alkynylzinc reagent to unactivated simple ketones under very mild conditions. The corresponding chiral tertiary propargylic

  • Highly Enantioselective Phenylacetylene Additions to Ketones Catalyzed by (<i>S</i>)-BINOL−Ti Complex

    日期:2004.11.1
    Ti(O(i)Pr)(4) is an effective chiral catalyst for the catalytic asymmetric addition of alkynylzinc to unactivated simple ketones. Good to excellent enantioselectivities were achieved. No previous case has been reported successfully using BINOL to catalyze the addition of phenylacetylene to unactivated ketones, and thus the utility of BINOL in asymmetric catalysis is expanded.
    容易获得且便宜的(S)-BINOL配体与Ti(O(i)Pr)(4)结合使用,是一种有效的手性催化剂,可将炔基锌催化不对称加成到未活化的简单酮上。实现了良好至优异的对映选择性。没有以前的案例成功报道过使用BINOL催化苯乙炔加成到未活化的酮上的情况,因此BINOL在不对称催化中的应用得到了扩展。

    日期:2008.2
    Polymer-supported Schiff-base of optically active amino alcohols was used as chiral ligands in the enantioselective addition of alkynylzinc to simple ketones. At a 10 mol % ligand loading, chiral propargylic alcohols with moderate to good ee values (up to 89%) were produced. The polymeric catalyst could be recycled many times and used for further reactions.

    New chiral oxazolidine ligands have been derived conveniently from natural amino acids in good yields. Their use in the enantioselective addition of phenylacetylene to aromatic ketones has been tested with the best ee being up to 88%. We provide a simple, practical and inexpensive method to generate chiral tertiary propargylic alcohols.

  • Enantioselective alkynylation of aromatic ketones promoted by (S)-phenylalanine-derived β-amino alcohol
    作者:Lei Liu、Yong-feng Kang、Rui Wang、Yi-feng Zhou、Chao Chen、Ming Ni、Mao-zhen Gong

    日期:2004.11
    (S)-(-)-2-Amino-1,1,3-triphenylpropanol 3c, which is readily available from L-Phe, was found to be effective in catalyzing the addition reaction of an alkynylzinc reagent to aromatic ketones with up to 80% ee of the thus produced chiral tertiary propargylic alcohols. Unlike previous reports, 3c does not require the use of an additional central metal (other than zinc itself) and the prepreparation of an alkynylzinc. This has greatly simplified the experimental procedure for this reaction. (C) 2004 Elsevier Ltd. All rights reserved.
