described α-acetyl-α-diazomethanesulfonamide was employed in a three-component reaction with azide-containing benzaldehydes and propargylamines. Besides the initial formation of the triazole core, the reaction proceeded further, in uncatalyzed fashion at room temperature and yielded, after intramolecular azide–alkyne click reaction novel, structurally intriguing bistriazoles.
先前描述的 α-乙酰基-α-重氮甲磺酰胺用于与含叠氮化物的苯甲醛和丙炔胺的三组分反应。除了最初形成三唑核外,反应在室温下以未催化的方式进一步进行,并在分子内叠氮化物-炔烃点击反应后产生结构有趣的新型双三唑。
