A recently discovered radical fragmentation of 2-fluoro-6-pyridinoxy derivatives allows a new highly stereoselective and convergent route to (E)-vinylsulfones from allylic alcohols. Reductive desulfonylation or nickel-catalyzed couplings furnish di- and trisubstituted (E)- and (Z)-alkenes.
最近发现的 2-氟-6-吡啶氧基衍生物的自由基片段化,为从烯丙醇合成(E)-乙烯基砜提供了一条新的高立体选择性和高收敛性的途径。还原脱磺酰基或镍催化偶联可以得到二取代和三取代的(E)-和(Z)-烯烃。
