Synthetic studies on the pederin family of antitumour agents. Syntheses of mycalamide B, theopederin D and pederin

The synthesis of mycalamide B, theopederin D and pederin, which are antitumour agents was discussed. All three compounds were 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. Ground state conformational models were proposed to explain the stereoselectivity of the reactions. The absolute and relative stereochemistry of the compounds has been established by X-ray crystallography and NMR studies.

A synthesis of theopederin D and a formal synthesis of pederin

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.
