## Abstract Bicyclo[2.1.0]pent‐5‐yl methyl ketones undergo two thermal isomerization reactions. The __endo‐exo__ stereomutation follows the ring‐flip path in better than 90%, with inversion of the configuration of the angular carbon atoms by cleavage and reclosure of the central bond. Stereomutatio
