<p>The C19 aconitine-type diterpenoid alkaloids (–)-talatisamine, (–)-liljestrandisine, and (–)-liljestrandinine have been prepared in 31, 30, and 33 steps, respectively, from phenol. The synthetic approach features a 1,2-addition/semi-pinacol rearrangement as the key fragment coupling tactic. These efforts have also resulted in a correction to the original structure assignment of (–)-liljestrandisine.</p>

Total Syntheses

The diterpenoid alkaloids serve as a rich source of synthetic targets for organic chemists, due to the intriguing structure of the overlapping ring systems, along with biological activities commonly associated with compounds of this group. Fifteen total syntheses and numerous synthetic studies towards construction of ring fragments have been reported since 2010. This review article gives a brief overview of diterpenoid alkaloids and summarizes the recent synthetic efforts.1 Introduction1.1 Structural Classification and Biosynthetic Origin1.2 Structure Elucidation of the Aconitum Alkaloids2 Total Syntheses2.1 C18-Diterpenoid Alkaloids2.2 C19-Diterpenoid Alkaloids2.3 C20-Diterpenoid Alkaloids3 Strategies To Synthesize Ring Systems3.1 Radical-Based Cyclizations3.2 Ruthenium-Mediated Enyne Cycloisomerization3.3 Reductive Coupling3.4 Diels–Alder Reactions3.5 Oxidative Dearomatization/Diels–Alder Sequence3.6 Transannular Aziridation3.7 Intramolecular [5+2] Cycloaddition3.8 Miscellaneous4 Conclusion
