A 1,3-dipolar cycloaddition of 2-methylquinoline, tert-butyl nitrite (TBN) and alkynes or alkenes for the synthesis of biheteroaryls containing both isoxazoline/isoxazole and quinoline motifs has been developed. In this protocol, TBN serves as a convenient N-O source to convert 2-methylquinoline into intermediate nitrile oxides in situ.
开发了一种通过 2-甲基喹啉、叔丁基硝酮(TBN)和炔烃或烯烃的 1,3-偶极环加成反应来合成同时含有异噁唑啉/异噁唑和喹啉结构的双杂芳基的方法。在该方案中,TBN 作为一种方便的 N-O 源,可将 2-甲基喹啉原位转化为中间腈氧化物。
