pyrazoloquinazolinone derivatives. The strategy involves a one-pot reaction wherein the N-tosylhydrazone and its corresponding diazo derivative are generated in situ, followed by an intramolecular 1,3-dipolar cycloaddition–ring expansion to provide the pyrazolo-[1,5-c]quinazolinone motif. This approach enables straightforward access to a diverse range of highly functionalized N-heterocyclic compounds
我们开发了一种无过渡金属的方法来构建吡唑并喹唑啉酮衍生物。该策略涉及一锅反应,其中原位生成N-甲苯磺酰腙及其相应的重氮衍生物,然后进行分子内 1,3-偶极环加成环扩展以提供吡唑并-[1,5- c ]喹唑啉酮基序。这种方法能够以良好的产率(高达 92%)直接获得各种高度功能化的 N-杂环化合物。
