A general modular approach to the members of the pederin family of antitumour agents is exemplified by syntheses of mycalamide B and theopederin D as well as a formal synthesis of pederin. All three compounds are prepared from 6-lithio-2,3-dimethyl-4-phenylselenomethyl-3,4-dihydro-2H-pyran and 2-(3-chloropropyl)-3,3-dimethyl-3,4-dihydro-2H-pyran-4-one.
