Stereoselective synthesis of the atropisomers of myristinin B/C

reaction: see text] The first stereoselective synthesis of a potent DNA damaging agent, (-)-myristinin B/C, has been accomplished. This efficient synthesis allowed for unambiguous confirmation of the structure and absolute stereochemistry of the atropisomeric natural product. The antipode, (+)-myristinin B/C, was also synthesized, providing ample material for biological evaluation of both enantiomers.
