Highly diastereoselective cyclopentane construction: Enantioselective synthesis of the dendrobatid alkaloid 251F

We report the first total synthesis, and thus structural confirmation, of the dendrobatid alkaloid 251F (1), based on the retrosynthetic analysis illustrated (1 → → 4). Key observations in this synthesis are that both the Rh-mediated cyclization of 4 and
