On treatment with ButLi and HMPA, N-tert-butyl-N-benzyl-1-naphthamide undergoes cyclisation to a tricyclic enolate which reacts diastereoselectively with electrophiles to give substituted 2,3,3a,9b-tetrahydro-1H-benzo[e]isoindol-1-ones, the first example of an anionic cyclisation onto an aromatic ring.
在ButLi和HMPA的作用下,N-叔丁基-N-苄基-1-萘甲酰胺发生环化反应,生成三环烯醇,该烯醇与亲电试剂发生非对映选择性反应,生成取代的2,3,3a,9b-四氢-1H-苯并[e]异吲哚-1-酮,这是芳香环阴离子环化反应的第一个实例。
