2, 3‐Dichloro‐5, 6‐dicyano‐1, 4‐benzoquinone Mediated Tandem Oxidative‐Coupling/Annulation of Enaminones with 1, 3‐Diarylpropenes for the Synthesis of 3‐Allylchromones. Issue 28 (10th July 2019) - Cheng, Dongping
Abstract : The tandem reaction of enaminones with 1, 3‐diarylpropenes mediated by 2, 3‐dichloro‐5, 6‐dicyano‐1, 4‐benzoquinone (DDQ) is reported, which involves the oxidative coupling and the intramolecular cyclization reactions. It provides a convenient, efficient and metal‐free method for the synthesis of 3‐allylated chromones and quinolone with potential biological activities.
