A divergent and regiocontrolled Pd-catalyzed domino sequence involving an intramolecular N-arylation and an intermolecular Heck reaction has been developed, providing rapid access to functionalized benzodiazepine-2,5-diones 3. The starting materials were synthesized by the Ugi four-component reaction. An unprecedented X-ray structure of bispalladacycle 6 was documented.
已开发出一种涉及分子内N-芳基化和分子间Heck反应的发散性区域可控钯催化多米诺序列,可快速获得功能化的苯并二氮杂䓬-2,5-二酮3。起始原料通过乌吉四组分反应合成。记录了双钯环6前所未有的X射线结构。
