Two natural products with potential PDE5 inhibition activity, lorneic acids A and B, have been synthesized for the first time in high yield using a chiral amide stereocontrolled addition of aryl lithium to aldehyde as the key step, and the configuration of the chiral benzylic alcohol in lorneic acid B was determined to be S.
以芳基锂与醛的手性酰胺立体控制加成为关键步骤,首次高产率合成了两种具有潜在 PDE5 抑制活性的天然产物:氯尼酸 A 和 B,以及手性苯甲醇的构型。确定金叶酸B为S。
