A one-pot two-step microwave assisted synthesis of variously disubstituted 1,2,4-oxadiazoles from carboxylic acids and amidoximes is reported. This methodology is characterized by short reaction times, is versatile, robust and high-yielding and allows for the preparation of heterocycles with a stereocenter with 100% enantiomeric purity.
据报道,由一锅两步微波辅助从羧酸和a胺肟合成各种二取代的1,2,4-恶二唑。该方法的特点是反应时间短,用途广泛,稳定可靠且产率高,并且可以制备具有100%对映体纯度的立体中心的杂环。
