Preparative methodology is described for access to three different terpenoid-derived oxazolidin-2-ones 4, 8, and 11, of which the latter, obtained from camphene in four steps, provides virtually complete asymmetric induction when acting as a chiral auxiliary in Diels-Alder cycloaddition reactions with cyclopentadiene.
