AbstractSerendipitous findings of an acid mediated skeletal rearrangement of bicydo-beta-ketoester having cyclopropyl ring to access fused tricyclic gamma-butyrolactones has been described. This novel transformation has been optimized to 30 mol% p-toluenesulfonic acid (p-TSA) in toluene using Dean Stark apparatus, where the aldol condensation, cyclopropyl ring opening followed by cyclization took place in a single-pot operation. The resulting tricyclic compounds are interesting chemotype with natural product resemblance and may find useful applications in the future.
