synthesized as its levorotatory Me ester1 starting from (+)-2-ethoxycarbonyl-7,7-ethylenedioxybicyclo[3.3.0]octan-3-one3, which was obtained by treating (±)-3 with baker's yeast. The absolute configuration of pentalenolactone E Me ester was established as depicted in1.
从(+)-2-乙氧基羰基-7,7-乙撑二氧双环[3.3.0] octan-3-one 3出发,合成戊二酸内酯E的天然对映体,作为其左旋Me酯1,其通过处理(±)获得- 3与面包酵母。戊烯戊内酯E Me酯的绝对构型如图1所示。
