A one‐pot four‐component synthesis of 6‐aryl‐6H‐dibenzo[e,i][1,3,7,2]oxadiazaborecin‐8(7H)‐ones is described. Heating a mixture of isatoic anhydride and a benzylamine afforded the corresponding anthranilamide derivative, which was condensed with a 2‐hydroxybenzaldehyde and an arylboronic acid under solvent‐free conditions to produce bridgehead bicyclo[4.4.0]‐boron heterocycles in good to excellent
描述了6-芳基-6 H-二苯并[ e,i ] [1,3,7,2]恶二氮杂硼酸-8(7 H)-one的一锅四组分合成方法。加热等酸酐和苄胺的混合物,得到相应的邻氨基苯甲酰胺衍生物,将其与2-羟基苯甲醛和芳基硼酸在无溶剂的条件下缩合,以良好的产率获得桥头双环[4.4.0]-硼杂环。X射线单晶分析最终确定了所获得的桥头双环6-6杂环化合物的结构。
