Oroidin derived pyrrole imidazole marine alkaloids (PIAs) are attractive targets for synthetic organic chemists because of their structural complexity and diversity as well as their interesting biological activities. A number of efforts have been carried out to develop strategies for the synthesis of these natural products. Members of PIAs ( eg., 2-7) which contain tetracyclic ring systems possessing characteristic cyclic guanidine or urea moieties show significant biological activities including anticancer activity and agonistic activity against the adrenoceptor. In this review investigations of the total synthesis of the representative tetracyclic PIAs dibromophakellin (2) and dibromophakellstatin (3) are described.

Ingenol is a diterpenoid with unique architecture and has derivatives possessing important anticancer activity, including the recently Food and Drug Administration–approved Picato, a first-in-class drug for the treatment of the precancerous skin condition actinic keratosis. Currently, that compound is sourced inefficiently from Euphorbia peplus. Here, we detail an efficient, highly stereocontrolled synthesis of (+)-ingenol proceeding in only 14 steps from inexpensive (+)-3-carene and using a two-phase design. This synthesis will allow for the creation of fully synthetic analogs of bioactive ingenanes to address pharmacological limitations and provides a strategic blueprint for chemical production. These results validate two-phase terpene total synthesis as not only an academic curiosity but also a viable alternative to isolation or bioengineering for the efficient preparation of polyoxygenated terpenoids at the limits of chemical complexity.

The first synthesis of a natural triterpenoid saponin bearing N-acetylglucosamine, albidoside A, which is isolated from the roots of Acacia albida, is concisely achieved in a convergent strategy. Preliminary pharmacological research shows anticancer activity against HL-60, MCF-7, MDA-MB-231, Hep-2, and Hela cell lines. In particular, it exhibited good selectivity, which is five times more cytotoxic toward Hep-2 cells (IC50 = 8.91 μM) than the Hela cell line.
