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.
金催化的1,4-烯炔的氧化环化作用被用于研究瓦格纳-梅尔温重排的γ效应。实验和理论工作均表明,在γ位上的金取代基可以指导抗β取代基的立体有择1,2-移位,而不管其内在特性如何。
