The first total synthesis of the stress factor (+)-hydroxymyoporone (4) is presented. The key step is an asymmetric allylation of the methyl ketone 10 which proceeds with excellent selectivity and yield. In addition, it was proven that the allylation assignment of the absolute configuration of hydroxymyoporone published in the natural literature is incorrect; the correct structure of the (+)-enantiomer is depicted in the structural formula 4.
