    One Pot Synthesis of Optically Active 4-Isoxazolines by Asymmetric Addition of Alkynylzinc Reagents to Nitrones Followed by Cyclization
    摘要:
    One pot synthesis of optically active 4-isoxazolines was achieved by asymmetric addition of alkynylzinc reagents to nitrones utilizing di(t-butyl) (R,R)-tartrate as a chiral auxiliary followed by cyclization. By addition of dimethylzinc, the cyclization step was accelerated to afford the corresponding 4-isoxazolines with up to 93% ee. Furthermore, a cyclized zinc intermediate could be trapped with formaldehyde to give the corresponding 2,3,4,5-tetrasubstituted 4-isoxazoline with 85% ee.

  • A Lewis acid/metal amide hybrid as an efficient catalyst for carbon–carbon bond formation
    作者:Yasuhiro Yamashita、Yuki Saito、Takaki Imaizumi、Shū Kobayashi
    DOI:10.1039/c4sc01332h
    日期:——
    synthetically useful propargyl hydroxylamines. It is noted that neither the Lewis acids (InCl3, In(OTf)3) nor the metal amides (In(HMDS)3) have activity; only the hybrids worked well, and the catalytic activity of the hybrids was shown to be much higher than that of previously reported catalysts for this reaction. The concept of a Lewis acid/metal amide hybrid as a catalyst may be expanded to broad acid/base
    尽管路易斯酸和金属酰胺是最常用的金属种类之一,但据信它们在结合时不相容。在这里,我们描述了一种路易斯酸/金属酰胺杂化物,它在同一金属络合物中包含吸电子基团和碱性和庞大的氮官能团,作为一种新型催化剂。我们已经合成了路易斯酸/金属酰胺杂化物In(N(SiMe 3)2)2 Cl(In(HMDS)2 Cl)和In(HMDS)2 OTf,它们对硝酮与末端炔烃的反应显示出优异的催化活性。得到合成上有用的炔丙基羟胺。注意,路易斯酸(InCl 3,In(OTf)3)和金属酰胺(In(HMDS)3)有活动;仅杂化物工作良好,并且该杂化物的催化活性显示出比先前报道的用于该反应的催化剂的催化活性高得多。路易斯酸/金属酰胺杂化物作为催化剂的概念可以扩展到广泛的酸/碱催化。
  • InBr3-catalyzed direct alkynylation of nitrones with terminal alkynes: an efficient synthesis of N-hydroxy-propargyl amines
    作者:Du-Ming Ji、Ming-Hua Xu
    DOI:10.1016/j.tetlet.2009.03.206
    日期:2009.6
    An InBr3-Catalyzed direct and efficient alkynylation of nitrones with terminal alkynes was developed. The process enables practical synthesis of a wide range of synthetically useful N-hydroxy-propargyl amine derivatives in good yields under mild conditions. The application of this method to optically active propargylic N-hydroxyamines syntheses was also described. With chiral nitrones, good diastereoselectivities were obtained. Moreover, the first chiral indium(III) complex-catalyzed asymmetric alkynylation of nitrone was achieved with moderate enantioselectivity. (C) 2009 Elsevier Ltd. All rights reserved.

    Asymmetric addition of diphenylzinc to C-alkynyl nitrones was achieved by utilizing di(t-butyl) (R,R)-tartrate as a chiral auxiliary to afford the corresponding optically active (S)-N-(1-phenyl-3-substituted prop-2-ynyl)hydroxylamines. By the addition of a product-like additive, enantiomeric enhancement was observed. A mixed zinc reagent, PhZnMe, improved the enantioselection to afford hydroxylamines in up to 92% ee.

    日期:2016.8.5
    New catalytic methods for the synthesis of 4-isoxazolines have been developed via catalytic intramolecular cyclizations of propargylic N-hydroxylamines. The reactions proceed rapidly in less than 1 h at room temperature in the presence of 5 mol % (PPh3)AuCl/5 mol % AgOTf or 5 mol % (PPh3)AuNTf2. This process features an efficient route to 4-isoxazolines with high yields, short reaction times, and mild
