N2 - A free-radical cyclization of a tricyclic 18,19-bisnor-9β-podocarp-13-en-12-one that was derived from (R)-(-)-4,4a,7,8-tetrahydro-4a-methyl-2,5(3H,6H)-naphthalenedione and that possessed a C-7α (1-bromo-2-ethoxy)ethoxy group led to a tetracyclic intermediate possessing a protected 7α,16-lactol and suitable functionality for a quassinoid synthesis.
