General route to 4a-methylhydrofluorene diterpenoids: Total syntheses of (±)-taiwaniaquinones D and H, (±)-taiwaniaquinol B, (±)-dichroanal B, and (±)-dichroanone

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).

First Total Synthesis of the 4a-Methyltetrahydrofluorene Diterpenoids (±)-Dichroanal B and (±)-Dichroanone

(Matrix presented) A simple synthesis of the 4a-methyltetrahydrofluorene diterpenoids (±)-dichroanal B and (±)-dichroanone has been achieved through a common hexahydrofluorenone intermediate obtained via Pd(0)-catalyzed reductive cyclization of a substituted 2-(2-bromobenzyl) methylene cyclohexane.
