Homolytic demercuration of the 1,2-dioxolanes 14a and 14b in the presence of oxygen leads preferentially to endoperoxidee 17 (both epimers at C*) which upon reduction affords 8--prostaglandin F2α and the C(15)-epimer, a result in accord with a previous mechanistic proposal.
在氧引线的存在下1,2-二氧戊环14a和14b的均裂脱汞优先地endoperoxidee 17(差向异构体都在C *),其在还原得到8- -前列腺素˚F 2α和C(15)差向异构体,其结果是与先前的机械建议一致。
