cyclopentane B ring; it is also applicable to the synthesis of the wide variety of existing taiwaniaquinoids. Utilizing this, (−)-taiwaniaquinone A, F, G, and H, (−)-taiwaniaquinol B, and (−)-dichroanone have been synthesized from (+)-abietic acid. The versatility of this strategy allows us to propose the abietane C7–C8 cleavage as a possible biosynthetic pathway to this type of rearranged diterpenes; this
