ate (4), a linear methyl-branched intermediate with its chiral center at C7, and with two different functional groups at the ends of the chain, has been synthesized from (+)-aromadendrene in nine steps. A Baeyer–Villiger oxidation and a Grob fragmentation are the key reactions in this transformation. Intermediate 4 has been applied in the synthesis of three linear methyl-branched pheromones, (i) (
