Synthesis of the rearranged drimane sesquiterpenoids (+)-avarol and (+)-avarone from Wieland-Miescher ketone is described. This synthetic sequence provides convenient access to the natural enantiomers and, based on comparison of the optical rotation of synthetic avarol dimethyl ether with literature data, affords material of significantly higher optical rotation than a natural source.
