tetrahydroisoquinoline derivatives using a catalytic amount of ceriumammoniumnitrate (CAN) and a stoichiometric amount of NaBrO3 as oxidants was developed. The reaction is significantly influenced by the substituent groups on the phenyl ring. While electron-withdrawing groups on the phenyl ring can lower the reactivities of the substrates, electron-donating groups on the phenyl ring can dramatically promote
开发了一种高效且可扩展的方法,通过使用催化量的硝酸铈铵 (CAN) 和化学计量的 NaBrO 3作为氧化剂,通过四氢异喹啉衍生物的苄基氧化来合成 3,4-二氢异喹啉-1( 2 H )-酮。该反应受苯环上的取代基的显着影响。虽然苯环上的吸电子基团可以降低底物的反应活性,但苯环上的给电子基团可以显着促进氧化速率。
