    Synthesis of 2-TIPS-oxazol-5-ylboronic acid pinacol ester: efficient route to 5-(het)aryloxazoles via Suzuki cross-coupling reaction
    摘要:
    A facile synthetic route to the new 2-TIPS PS-oxazol-5-ylboronic acid pinacol ester was described herein. Its reactivity toward Suzuki cross-coupling reaction was studied to provide various 5-(het)aryloxazoles. A wide range of functions on the aryl moiety are tolerated. (C) 2009 Elsevier Ltd.

  • Reaction Conditions for the Regiodivergent Direct Arylations at C2‐ or C5‐Positions of Oxazoles using Phosphine‐Free Palladium Catalysts
    作者:Xinzhe Shi、Jean‐François Soulé、Henri Doucet
    DOI:10.1002/adsc.201900641
    日期:2019.10.22
    The higher reactivity of C5‐H bond of oxazole as compared to the C2‐H bond in the presence of Pd(OAc)2/KOAc system is consistent with a concerted metalation deprotonation mechanism; whereas the C2arylation likely occurs via a simple base deprotonation of the oxazole C2‐position. Then, from these C2‐ or C5‐arylated oxazoles, a second palladium‐catalyzed direct C−H bond arylation affords 2,5‐diaryloxazoles
    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[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。
