Isoprostanes (iPs) are a group of natural products formed in vivo by a free-radical oxygenation of arachidonic acid. They are isomeric with prostaglandins; whereas enzymatically produced prostaglandins, such as PGF2α have the two side chains in the trans stereochemistry, the side chains of the isoprostanes are mostly in the cis configuration. A novelsynthesis of iPs is described and illustrated with

日期:1982.1
Reaction of 1,1-dimethoxy-2-butyne (II) with sodiummethoxide in dimethyl sulfoxide at 100° yields (1E)-1,3-dimethoxybutadiene (III) (20–30%). The diene III undergoes ready Diels-Alder reaction with maleic anhydride, N-phenyltriazolinedione and dimethyl acetylenedicarboxylate.
