The first asymmetric total syntheses of sesquiterpene lactones (+)-eudesmadiene-12,6-olide (1) and (+)-frullanolide (2) have been accomplished from 4-bromo-2-methoxyphenol (5) in 12 and 13 synthetic steps, respectively, and the absolute configurations of these two natural products were determined.
倍半萜烯内酯(+)-大马士革烯12,6-内酯(1)和(+)-富勒烯内酯(2)的第一个不对称总合成是由4-溴-2-甲氧基苯酚(5)在12和13个合成物中完成的步骤,并确定这两种天然产物的绝对构型。
