New synthetic methods for .gamma.-geraniol, boll weevil pheromone, and .alpha.-damascone employing 2-(hydroxymethyl)-4-(phenylthio)-1-butene as a building block
New synthetic methods for .gamma.-geraniol, boll weevil pheromone, and .alpha.-damascone employing 2-(hydroxymethyl)-4-(phenylthio)-1-butene as a building block
A sequence of allylation, the Wacker reaction, and desulfonylation of homoallyl sulfones provided a new synthetic method for the α,β,γ,δ-unsaturated ketone system often encountered in natural products. This procedure was successfully applied to ionone and irone synthesis.
