Although each new taiwaniaquinoid isolated has the same rearranged abietane nucleus, the mechanism of its formation is not necessarily the same. For example, the natural products isolated from Taiwania cryptomerioides are regarded as 5(6 → 7)-abeoabietane diterpenoids or 6-nor-5(6 → 7)-abeoabietane diterpenoids, in contrast to standishinal (shown below) which is a 6(7 → 11)abeoabietane. The position of the formyl group in the natural products isolated from Salvia dichroantha is not accounted for by either mechanism; if dichroanone and dichroanal are formed by the same process, then they are most likely the result of a 6-nor-5-(6-7) type rearrangement.{A figure is presented}

9 however, in our hands, the yield of this two-step procedure varied, presumably due to the stability of the intermediate hydrazone.
