from a medicinal plant Pinelliae tuber, has potent adjuvant activity. The absolute configuration of pinellic acid was expected by derivatization of this compound and CD exciton chirality method. A convergent synthetic route to pinellic acid has been developed via regioselective asymmetric dihydroxylation and stereoselective reduction. The absolute configuration of pinellic acid was determined to be 9S
从药用植物半夏中分离出的松香酸(1)具有有效的佐剂活性。通过该化合物的衍生化和CD激子手性法可以预期到松果酸的绝对构型。通过区域选择性的不对称二羟基化和立体选择性的还原,已经开发出一种聚合的合成壬二酸的途径。通过与天然和合成化合物的光谱数据进行比较,确定了半乳糖酸的绝对构型为9 S,12 S,13 S。
