Sport of kings: A new gold(I)‐catalyzed transformation has been developed that occurs under mild conditions and proceeds by an expected substituent “castling” (see red and blue circles in scheme) to give efficient access to benzo[b]furans from the easy to obtain 3‐silyloxy‐1,5‐enynes (IPr=N,N′‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene, NTf2=bis(trifluoromethylsulfonylimide).
国王运动:已经开发了一种新的金(I)催化的转化,该转化在温和的条件下发生,并通过预期的取代基“浇铸”进行转化(请参见方案中的红色和蓝色圆圈),以有效地从中获得苯并[ b ]呋喃容易获得的3-甲硅烷氧基-1,5-炔烃(IPr = N,N'-双(2,6-二异丙基苯基)咪唑-2-亚烷基,NTf 2 =双(三氟甲基磺酰亚胺)。
