An approach to 2,3-benzotropone from 1-benzosuberone via palladium(II)-catalyzed aerobic dehydrogenation was developed. This method first provided a catalytic route to various 2,3-benzotropones from their corresponding 1-benzosuberones in good yields. In addition, the reaction could be applied to a one-pot Diels–Alderreaction with maleimide, providing a complex benzobicyclo[3.2.2]nonenone in ≤90%
开发了一种通过钯 (II) 催化有氧脱氢从 1-苯并环庚酮生产 2,3-苯并托酮的方法。该方法首先提供了从相应的 1-苯并环庚酮制备各种 2,3-苯并环酮的催化路线,且产率良好。此外,该反应可应用于与马来酰亚胺的一锅狄尔斯-阿尔德反应,以≤90%的产率提供复杂的苯并双环[3.2.2]壬烯酮。还进行了支持我们提出的机制的动力学分析,强调了所开发的合成途径的稳健性。
