Silver‐catalyzed stereoselective [3+2] cycloadditions between mono‐substituted cyclopropyl‐indanimines and aldehydes are reported. The stereochemical course of the reaction is rationalized with a cyclic transition state. The resulting indanimine cycloadducts are not readily hydrolyzed unless external aldehydes are present with the silver catalyst. Notably, this hydrolysis process leads to a change
