Abstract
Daphnimacropodines A-C are members of a small but structurally distinct subfamily of Daphniphyllum alkaloids. Their congested polycyclic skeletons, and two vicinal quaternary stereocenters, present significant synthetic challenges. This paper describes two stereoselective approaches to constructing the tricyclic core structures of daphnimacropodines, achieved through a straightforward Rh-catalyzed [4 + 3] cycloaddition using simple building blocks. This work also highlights an intramolecular Heck reaction that rapidly assembles the cyclohexane ring moiety, a Tsuji-Trost allylation that forged the critical C-8 quaternary stereocenter, an efficient hetero-Diels-Alder reaction, and an intramolecular nucleophilic addition, which paved the way to the key cyclopentane ring. The assembly of the tetrahydropyrrole motif was also investigated.

Abstract
Daphniphyllum alkaloids (DAs) are interesting molecules with rich molecular skeletons and diverse biological activities. Since their discovery, phytochemists have isolated, purified, and identified more than 350 DAs. Synthetic chemists, attracted by the structure and activity of DAs, have accomplished many elegant synthetic jobs. Herein, we summarize work on the isolation, structural identification, bioactivity testing, and synthesis of DAs from 2018 to 2023, with the aim of providing a reference for future studies.
