a, The protosteryl–dammarenyl cation dichotomy in triterpene reaction pathways and their relationship to lanosterol and euphol. b, Examples of structural diversity originating from E-ring expansion of the dammarenyl cation, showing the relationship between the final scaffolds and the shared intermediatory carbocations. c, Carbon numbering and ring nomenclature used in this Article. The red asterisk in b indicates a cation referred to in Fig. 5.
