of seven biologically important lignan natural products, including (-)-arctigenin, (-)-matairesinol, and (-)-alpha-conidendrin, by way of a highly stereoselective domino radical sequence is presented. The reported stereochemistry of the natural product 7-hydroxyarctigenin is shown to be erroneous; a diastereoisomeric structure is assigned to the natural product.
[反应:见正文]通过高度立体选择性的多米诺基自由基序列,提出了7种具有重要生物学意义的木脂素天然产物的总合成物,包括(-)-arctigenin,(-)-matairesinol和(-)-alpha-conidendrin。据报道,天然产物7-羟基arctigenin的立体化学是错误的。非对映异构结构被分配给天然产物。
