Both the enantiomers as well as the racemate of 3-butyl-7-hydroxyphthalide (1) were synthesized, and the absolute configuration of the naturally occurring (−)-1 (a weakly cytotoxic metabolite of Penicillium vulpinum) was identified as S.
合成了 3-丁基-7-羟基
苯酞(1)的对映体和外消旋体,并确定了天然存在的 (-)-1(Penicillium vulpinum 的一种弱细胞毒性代谢物)的绝对构型为 S。
