How is Styrax (CAS: 8046-19-3) typically synthesized?

Styrax (CAS: 8046-19-3) is typically synthesized through the chemical transformation of rosin acid or its derivatives. Common methods include esterification of rosin acid with ethanol, followed by hydrogenation to form styracin. The synthesis involves the use of catalysts such as palladium on carbon to achieve high selectivity and yield. The process is conducted under mild conditions to maintain the integrity of the fragrance compound.
