The stereoselective synthesis of C1–C17 fragment of salinomycin is achieved. The strategy employs a desymmetrization approach and utilizes an intramolecular oxetane opening reaction with O-nucleophile to result in the tetrahydropyran skeleton as the key step.

addition into the natural product's α,β-unsaturatedlactone. Although pironetin's α,β-unsaturatedlactone is involved in its binding to tubulin, the structure-activity relationship at different positions of the lactone have not been thoroughly evaluated. For a systematic evaluation of the structure-activity relationships at the C4 and C5 positions of the α,β-unsaturatedlactone of pironetin, twelve analogues
