Aiming at a stereocontrolled biomimetic synthesis of isoprostanes a fully stereocontrolled 8,12-free radical cyclization has been achieved via intermediate 10 by annulating an endocyclic radical to a butenolide acceptor double bond. In this way ent-12-epi-PGF2α(ent-2) can be prepared.
针对异前列腺素的立体控制仿生合成,已经通过中间体10通过使内环自由基与丁烯酸内酯双键环合实现了完全立体控制的8,12-自由基的环化。以这种方式ENT -12-外延-PGF 2α(ENT - 2)可以被制备。
