Gold‐Catalyzed Oxidative Cyclizations on 1,4‐Enynes: Evidence for a γ‐Substituent Effect on Wagner–Meerwein Rearrangements

Abstract

Gold-catalyzed oxidative cyclizations of 1,4-enynes were used to study the γ-effect on the Wagner–Meerwein rearrangement. Both experimental and theoretical work disclose that a gold substituent in the γ-position can direct a stereospecific 1,2-shift of the anti-β-substituent regardless of its intrinsic properties.
