Sumnary: 4-Acetoxytricyclo[4.1.0.02y7 ]hept-4-en-3-one (S), a valence isomer of 2-acetoxytropone, was synthesized. Upon heating in pyridine at 15O"C, 3 rearranged into 1-acetoxybicyclo[3.2.O]hepta-3,6-dien-\*-one (9); the mechanism of which was examined by means of deuterium labeling experTments. Re
