An efficient synthesis of (−)-chrysolic acid and (+)-isofregenedol has been achieved from zamoranic acid and sclareol. The characteristic tetrahydronaphtalenic system was obtained by use of a cationic rearrangement of bicyclic systems adequately functionalized. The absolute configuration of the natural products was established using Sharpless asymmetric epoxidation.
由扎莫拉酸和香紫苏醇已经实现了(-)-酚酸和(+)-异泛醇的有效合成。通过使用适当官能化的双环系统的阳离子重排获得了特征性的四氢萘烷体系。天然产物的绝对构型是使用Sharpless不对称环氧化法确定的。
