An efficient total synthesis of scrodentoid A was accomplished starting from a Hagemann's ester and a substituted (2-bromoethyl)benzene. Key reactions in this synthesis include C-alkylation of the Hagemann's ester, 6-endo-Trig cationic cyclization of an enone and Lewis acid promoted isomerization of a cis-fused ketone.

A simple convergent and general method has been developed for the synthesis of (+/-)-isopisiferin (1c), a rearranged abietane diterpene, having a hexahydrodibenzocyclohepetene ring system, and the related model systems (1a) and (1b), through the respective enolisable tricyclic ketone mixtures (12c) and (13c), (12a) and (13a), and (12b) and (13b), obtained from the corresponding easily accessible 2-arylethyl-3,3-dimethylcyclohexanones (7c), (7a), and (7b).Demethylation of the styrenoid ethers (15b) and (15c) under acid conditions gave the tetracyclic dienones (17b) and (17c) through Ar1-5 cyclisation.
