    Unique Regioselectivity in the C(sp3)–H α-Alkylation of Amines: The Benzoxazole Moiety as a Removable Directing Group
    摘要:
    The benzoxazol-2-yl- substituent was found to act as a removable activating and directing group in the Ir-catalyzed alkylation of C(sp(3))-H bonds adjacent to nitrogen in secondary amines. It can be easily introduced by oxidative coupling or by an SNAr reaction, and it can be removed by hydroxide or by hydride reduction. For 1,2,3,4-tetrahydroisoquinolines, activation exclusively takes place in the 3-position. A variety of activated as well as unactivated terminal olefins are suitable reaction partners.

  • Amination of Benzoxazoles and 1,3,4-Oxadiazoles Using 2,2,6,6-Tetramethylpiperidine-N-oxoammonium Tetrafluoroborate as an Organic Oxidant
    作者:Sebastian Wertz、Shintaro Kodama、Armido Studer
    DOI:10.1002/anie.201104735
    日期:2011.11.25
    No transition metals are necessary to convert benzoxazoles and 1,3,4‐oxadiazoles into the corresponding pharmacologically interesting 2‐aminated heterocycles by formal direct C(2)‐amination using tetramethylpiperidine‐N‐oxoammonium tetrafluoroborate (TEMPO+BF4−) as an oxidant (see scheme; TEMP=2,2,6,6‐tetramethylpiperidine; TfOH=trifluoromethanesulfonic acid).
    没有过渡金属是必要通过正式直接C(2)使用-amination到tetramethylpiperidine-苯并恶唑和1,3,4-恶二唑转化成相应的药理学上感兴趣的2-胺化杂环Ñ -oxoammonium四氟硼酸盐(TEMPO + BF 4 - ),为氧化剂(参见方案; TEMP = 2,2,6,6-四甲基哌啶; TfOH =三氟甲磺酸)。
  • Silver-Mediated Direct Amination of Benzoxazoles: Tuning the Amino Group Source from Formamides to Parent Amines
    作者:Seung���Hwan Cho、Ji���Young Kim、S.���Yunmi Lee、Sukbok Chang
    DOI:10.1002/anie.200903957
    日期:2009.11.16
    Going to the source: Formamides or parent amines were used as an amino group source for the silver‐mediated amination of benzoxazoles. Although reactions with formamides proceeded at high temperatures, the direct amination with amines took place under much milder conditions (see scheme). Optically active amino groups could also be installed without racemization.
    来源:甲酰胺或母体胺被用作氨基介导的苯并恶唑的银基胺化反应。尽管与甲酰胺的反应在高温下进行,但与胺的直接胺化反应却在温和得多的条件下进行(参见方案)。光学活性的氨基也可以不消旋地安装。

    A facile and transition-metal-free method was developed through merging the ring opening of benzoxazoles with secondary amines and N-bromosuccinimide (NBS) mediated oxidative cyclization toward the synthesis of 2-aminobenzoxazoles. NBS was selected as a powerful oxidant in the oxidative cyclization of ring-opening amidines to provide the desirable 2-aminobenzoxazoles in excellent yields (up to 94%).
