A copper‐catalyzedenantioselective arylative desymmetrization of prochiral cyclopentenes with diaryliodonium salts was developed. In the presence of a catalytic amount of a chiral copper–bisoxazoline complex, which was generated in situ, the reaction of 4‐substituted or 4,4‐disubstituted cyclopent‐1‐enes with diaryliodonium hexafluoroarsenates afforded the chiral arylated products in good yields with

The preparation and lithium amide-induced rearrangements of 1,2-dideuterated 4-substituted cyclopentene oxides 11 and 19 are described, providing insight into the deprotonation mechanisms operating in such systems. Highly enantioselective syntheses of 4-substituted cis-4-hydroxymethylcyclopent-2-en-1-ols 32a–c are described. Also described are asymmetric syntheses of prostaglandin precursor 40 and (+)-iridomyrmecin (48) via highly enantioselective rearrangement of the epoxide 3 and subsequent Ireland–Claisen rearrangement.
