Sažetak
The total synthesis of hedyotol A (1), a natural product isolated from Hedyotis lawsoniae (DC.) Wight et Arn. (Rubiaceae), was accomplished in a highly stereocontrolled manner. Key steps include an L-proline-catalyzed cross-aldol reaction and the biomimetic construction of a furofuran lignan skeleton through a quinomethide intermediate.
