Mycalamide B, a potent antitumour agent, was synthesized from cheap, readily available starting materials: ethyl lactate, ethyl isobutyrate, 4-chlorobutanal, and 4-chlorobutanoyl chloride. The trioxabicyclo[4.4.0]decane ring system was created by reaction of a methoxymethyl ether with a silyloxyoxirane induced by phosphorus pentoxide.

Theopederin D, a cytotoxic metabolite from a sponge of the genus Theonella, was synthesised in 14 steps (11.1% overall yield) from two advanced intermediates previously used in a synthesis of mycalamide B. A formal synthesis of pederin from similar intermediates is also reported.

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.
