Abstract A convenient, straightforward, and easy access to 2(2,3‐dimethoxy‐phenyl)cycloheptanone, which employs an heteroatom‐facilitated ortho‐lithiation coupled to a carbonyl transposition strategy, is reported. The synthetic approach avoids using very expensive reagents or difficult‐to‐prepare starting materials.
摘要 报道了一种方便、直接且容易获得 2(2,3-二甲氧基-苯基)环庚酮的方法,该方法采用杂原子促进的邻位锂化与羰基转座策略相结合。合成方法避免使用非常昂贵的试剂或难以制备的起始材料。
