An economical and practicalsynthesis of rac-(Z)-β-santalol was accomplished. The key coupling step is based on a Scriabine-inspiredreaction of a dienyl diacetate substrate and an alkene. The total synthesis was achieved in five steps (longest linear sequence) in 19 % overall yield from cyclopentadiene.
