Synthetic Studies of Zoanthamine Alkaloids
Summary
Zoanthamine alkaloids are a distinctive family of marine-derived natural products distinguished by a densely fused, multi-ring carbon framework and multiple stereocentres. Since their initial isolation, these molecules have posed formidable challenges to synthetic chemists owing to their architectural complexity and sensitive functionality. Over the past three decades, efforts have ranged from stepwise ring assembly to biomimetic cascade cyclisations, each aiming to improve step-economy, control stereochemical outcomes and enable late-stage diversification. Key strategies have included intramolecular cycloadditions, tandem Michael–aldol sequences and ring-closing metathesis, often in conjunction with chiral catalysts to achieve high enantioselectivity. These advances not only furnish access to the natural products themselves but also permit the synthesis of designed analogues for biological evaluation, thereby underpinning drug-discovery efforts targeting neuroprotective and anti-inflammatory activities.

The graph below shows the total number of articles in synthetic studies of zoanthamine alkaloids across all publications each year (not limited to Nature Index journals).
Technical terms
Zoanthamine alkaloids: A class of marine-derived polycyclic natural products characterised by a fused multi-ring framework and multiple stereocentres.
Enantioselective synthesis: A synthetic approach that preferentially forms one enantiomer over its mirror image, often using chiral catalysts or auxiliaries.
Michael addition–aldol sequence: A tandem reaction combining Michael addition and aldol condensation to rapidly build complex carbon skeletons.
Diels–Alder reaction: A cycloaddition process in which a conjugated diene reacts with a dienophile to form a six-membered ring with defined stereochemistry.
Biomimetic cyclisation: A strategy that replicates natural biosynthetic pathways to assemble intricate ring systems in a single operation.
About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
