3′‐Keto‐1‐nitro‐2‐phenylspiro[cyclopropane‐3,2′‐quinuclidine] was synthesized by a two‐step procedure from 2‐benzylidenequinuclidin‐3‐one. Ring‐opening reactions of the cyclopropane ring using a variety of N ‐, O ‐, and C ‐nucleophiles (amines, methoxide, nitromethanate, cyanide anions, and lithium diphenylcopper) were studied, and a general mechanism for the transformations is proposed.
