使用2摩尔%的Au(PPh 3)NTf 2从容易获得的炔丙基乙酸酯有效地制备了通用的线性α-碘代和α-溴代烯酮。该反应操作简便,底物范围广.在由脂肪族醛衍生的炔丙基乙酸酯的情况下观察到良好至优异的Z-选择性。(C)2008年由Elsevier Ltd.出版
Versatile linear alpha-iodo- and alpha-bromoenones are prepared efficiently from readily accessible propargylic acetates using 2 mol % of Au(PPh3)NTf2. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of propargylic acetates derived from aliphatic aldehydes.
