total syntheses of (+)-streptazolin 1 and its more stable dihydro derivative 2 were accomplished via an intramolecular aldol condensation strategy starting from readily available aminocyclopentenol (−)-7. The synthetic sequence included reductive amination, stereoselective epoxidation, intramolecular aldol (and condensation) reaction, and Wittig reaction. The overall yield for dihydro derivative 2 from
