We describe new methodology for the synthesis of both enantiomers of 7,7-dichlorobicyclo[3.2.0]hep-2-en-6-one and conversion of these compounds into stereochemically defined bicyclo[3.3.0]oct-2-en-7-ones and thence trisubstituted cyclopentanes. These are key intermediates for the synthesis of prostanoids, brefeldin and other cyclopentane-containing natural products.
我们描述了7,7-二氯双环[3.2.0] hep-2-en-6-one的两个对映异构体的合成以及将这些化合物转化为立体化学定义的双环[3.3.0] oct-2-en-的新方法7-ones,然后是三取代的环戊烷。这些是合成前列腺素,布雷菲德菌素和其他含环戊烷的天然产物的关键中间体。
