(3) of the insect toxin pederin (1) are described. An intramolecular directed aldol condensation was used to construct the tetrahydropyran ring in (+)-pederol dibenzoate (2). Better stereocontrol in the synthesis of (±)-benzoylpedamide (3) was achieved in which the stereochemistry at C-11 was introduced by a conjugate addition of TMSCN to the dihydropyranone (31). The synthesis of (±)-pederin from (±)-(3)
