A CONVENIENT ONE-POT SYNTHESIS OF 13-PERFLUOROALKYLATED RETINOIDS
摘要:
11,12-Dehydro-13-perfluoroalkylretinoate esters (and retinonitriles) have been prepared in one step assembly of the retinoid skeleton via the " 16 + 4" strategy for retinoid synthesis.

The reaction of fluorinated ylide-anions, generated from nucleophilic addition of organolithium compounds to perfluoroacylcyanomethyl enetriphenylphosphoranes 1, with iodine or 1,2-diiodoethane afforded perfluoroalkylated a-iodo-a,b-unsaturated nitriles in 70–97% yields.
