    摘要:
    氢氧化四丁基铵(TBAH)是氟化四丁基铵(TBAF)的一种高效,温和的替代品,用于由O-酰基酰胺基肟对1,2,4-恶二唑进行碱催化的环化反应。对于大多数3,5-取代的1,2,4-恶二唑,在室温下通过添加0.1当量的TBAH可以显着加速反应。该方法也更普遍地适用于允许更大范围的基板。另外,由于不存在氟化物,TBAH不会导致反应堆容器的腐蚀,因此更适合大规模合成。

  • Synthesis of 3,5-disubstituted-1,2,4-oxadiazoles using tetrabutylammonium fluoride as a mild and efficient catalyst
    作者:Anthony R Gangloff、Joane Litvak、Emma J Shelton、David Sperandio、Vivian R Wang、Kenneth D Rice

    日期:2001.2
    Tetrabutylammonium fluoride (TBAF) was found to be a mild and efficient catalyst for the synthesis of 3,5-disubstituted-1,2,4-oxadiazoles. Using 0.1–1.0 equivalents of TBAF in THF for 1–24 h at room temperature, alkanoyl- and aroyloxyamidines were converted in high yield to the corresponding 3,5-disubstituted-1,2,4-oxadiazoles. A variety of R and R′ substituents were investigated.
    发现四丁基氟化铵(TBAF)是合成3,5-二取代-1,2,4-恶二唑的温和而有效的催化剂。在室温下,使用THF中的0.1–1.0当量的TBAF,在室温下放置1–24小时,可以将烷酰基-和芳酰氧基am以高收率转化为相应的3,5-二取代-1,2,4-恶二唑。研究了各种R和R'取代基。
