    不含磷的钯催化剂在恶唑的C2或C5位上的区域发散性直接芳基化的反应条件
    摘要:
    据报道,恶唑的C 2或C 5的区域直接芳基化有两个反应条件。在这两种情况下,均使用无膦催化剂和廉价的碱,从而以中等至高收率获得芳基化的恶唑。使用Pd(OAc)2 / KOAc作为催化剂和碱,可观察到区域选择性C5-芳基化;而使用Pd(acac)2 / Cs 2 CO 3系统,芳基化发生在恶唑的C2位。与存在Pd(OAc)2 / KOAc系统时的C2-H键相比,恶唑的C5-H键具有更高的反应活性,这与协同的金属化去质子化机理是一致的。而C2芳基化可能是通过恶唑C2位的简单碱基去质子化。然后,从这些C2或C5芳基恶唑中,进行第二次钯催化的直接C H键芳基化,得到具有两个不同芳基的2,5-二芳基恶唑。我们还通过三个CH键功能化步骤将这些顺序的芳基化反应用于2-芳基菲[9,10- d ]恶唑的直接合成。还描述了2-芳基恶唑的芳基单元的Ru催化的CH芳基化。

    10-(Methoxyimino)phenanthrene-9-one 1 reacts thermally with the arylacetic derivatives 2(a-j) to yield the corresponding 1,4-benzoxazin-2-ones 4(a-d,f) and benzo[d]oxazoles 5(a-e,g). Similarly, reaction of the monoximes 7a, 7b with compounds 2a, 2d respectively affords 8a, 8b, while action of trans-stilbene on the monoximes 1, 7a, 7b leads to the 1,4-benzoxazines 10, 11, 13, obtained along with the

    (DMSO)-promoted catalyst-free oxidative C–N coupling and C–O coupling under oxidant-free conditions are outlined. This protocol is operationally simple and leads to various functionalized substituted imidazoles or oxazoles in good yields. To date, a very limited number of oxidation protocols have been established, where DMSO acts solely as a catalyst or an oxidant or both. In this report, DMSO is not only used
    概述了二甲亚砜 (DMSO) 促进的无催化剂氧化 C-N 偶联和无氧化剂条件下的 C-O 偶联。该方案操作简单,并且以良好的产率产生各种官能化的取代咪唑或恶唑。迄今为止,已经建立的氧化方案数量非常有限,其中 DMSO 仅充当催化剂或氧化剂或两者兼而有之。在本报告中,DMSO不仅用作C-N/C-O偶联剂,还用作这些氧化转化所需的氧化剂。因此,我们所证明的 DMSO 促进的无催化剂偶联转化有能力引领氧化偶联领域的新维度。
  • Synthesis of phenanthro[9, 10-d]oxazoles from 10-(methoxyimino)phenanthrene-9-one
    作者:Demetrios N. Nicolaides、Evangelia A. Varella、R. Wajih Awad
    DOI:10.1016/s0040-4020(01)87251-3
    日期:1993.8
    10-(Methoxyimino)phenanthren-9-one 3 easily reacts with the methyl substituted aromatics 4(a-d), as well as with alpha-bromo-p-xylene 6 and the alpha-substituted methyl derivatives 7(a-i), to afford in 5-64% yield the corresponding 2-aryl substituted phenanthro[9,10-d]oxazoles 5(a-g), most probably via a free radical reaction sequence. In several cases the unsubstituted oxazole 12 is also obtained, while reaction of compound 3 with the N-methyl substituted amines 7g and 14(ab) leads to the aminooxazoles 13 and 15(a,b) respectively.
  • A convenient strategy to 2,4,5-triaryl and 2-alkyl-4,5-diaryl oxazole derivatives through silver-mediated oxidative C O cross coupling/cyclization
    作者:Rajib Sarkar、Chhanda Mukhopadhyay
    DOI:10.1016/j.tetlet.2015.04.103
    日期:2015.6
    This is a silver(I) mediated C-alpha(sp(3))-H activation of primary amines followed by oxidative C-O cross coupling/cyclization for the construction of 2,4,5-triaryl and 2-alkyl-4,5-diaryl oxazole derivatives. The protocol has been successfully utilized to synthesize the oxazole derivatives in good to excellent yields. In this oxidative coupling, the silver species after the reaction was successfully re-synthesized and reused with almost a similar activity. (C) 2015 Elsevier Ltd. All rights reserved.
