A general and convergent route for the synthesis of the 4a-methylhydrofluorene diterpenoids has been established through a common hexahydrofluorenone intermediate (10) obtained via Pd(0)-catalyzed reductive cyclization of a substituted 2-(2-bromobenzyl) methylene cyclohexane (13). The strategy has been successfully utilized for the synthesis of (±)-taiwaniaquinones D (3) and H (5), (±)-taiwaniaquinol B (1), (±)-dichroanal B (7), and (±)-dichroanone (8).
