Totalsynthesis of the (R,R,R)- and (S,S,S)-enantiomers of the natural product schweinfurthin F has been completed. Comparisons of spectral data and optical rotations with those reported for the natural product, as well as a variety of bioassay data, allow assignment of the natural material as the (R,R,R)-isomer.
Methods and intermediates for preparing enantiomerically enriched Schweinfurthin analogs which are useful for the treatment of cancer, as well as novel Schweinfurthin analogs having anti-cancer activity, compositions comprising such analogs and therapeutic methods comprising administering such analogs.
