An enantioselective alkoxylation/Claisen rearrangement reaction was achieved by a strategic desymmetrization of 1,4‐dienes under the catalysis of (S)‐DTBM‐Segphos(AuCl)2/AgBF4. This reaction system was highly selective for the formation of 3,3‐rearrangement products, providing cycloheptenes with various substitutions in good yield and good to excellent enantioselectivity. This transformation was further
在(S)-DTBM-Segphos(AuCl)2 / AgBF 4的催化下,通过1,4-二烯的战略脱对称,实现了对映选择性烷氧基化/克莱森重排反应。该反应系统对形成3,3重排产物具有高度选择性,从而为
环庚烯提供了各种取代基,收率高,对映选择性很好。这种转变进一步扩展到了双环环基质,从而提供了轻松组装5、6和6,7稠合环系统的机会。
