Novel Synthesis of 3‐Indolylquinones catalyzed by Molecular Iodine under Ultrasonic Irradiation
摘要:
The conjugate addition reactions of indoles with quinones were catalyzed efficiently by molecular iodine under ultrasonic irradiation to afford 3-indolylquinones in good to excellent yields, which provided a novel, mild, convenient approach for the preparation of 3-indolylquinones.
