How is Peru balsam (CAS: 8007-00-9) typically synthesized?

Peru balsam (CAS: 8007-00-9) is not typically synthesized from scratch but is mostly obtained from natural sources, such as the balsamopodium tree. However, synthetic routes have been developed using terpene precursors. Common methods involve the condensation of pinene with acetaldehyde in the presence of a base to form α-pinene oxide, followed by the reduction of the oxide to form a mixture of terpenes, which can then be purified to yield Peru balsam.
