An unprecedented and efficient [4 + 3] cycloaddition of N-(ortho-chloromethyl)aryl amides with nitrones has been developed. This approach provides easy access to a series of seven-membered benzooxadiazepine derivatives in good to excellent yields (up to 99% yield) under mild reaction conditions.
一种前所未有的、高效的 N-(邻氯甲基)芳酰胺与硝酮的[4 + 3]环加成反应已经被开发出来。该方法在温和的反应条件下,以良好至优秀的收率(高达 99%),简便地得到了一系列的七元苯并噁二嗪衍生物。
