<dcterms:abstract>[EN]Highly efficient syntheses of the anti-cancer agent trans-β-elemene have been achieved by using the readily available (±)-limonene as starting material. The syntheses were achieved in only nine to eleven steps with good overall yields. The key step in these reaction sequences is a stereoselective radical cyclization, induced by titanocene chloride.</dcterms:abstract>
