(−)-Methyl 7β-hydroxykaurenoate (3) and its 4-demethyl acetate (−)-4 were both synthesized via methods that contained radical cyclization and intramolecular Diels-Alder reactions as key steps. Both compounds displayed potent neuroprotective activity against N-methyl-D-aspartate toxicity in cultured cortical neurons.
