Proposal for structural revision of several monosubstituted tricycloalternarenes

Braulio M. Fraga et al.

Summary: In this study, we identified several monosubstituted tricycloalternarenes with erroneous structures and proposed correction strategies. We also determined that mono-hydroxylated tricycloalternarenes can only exist at specific positions, and further determined the structures and configurations of several compounds.

Phaseocyclopentenones A and B, Phytotoxic Penta- and Tetrasubstituted Cyclopentenones Produced by Macrophomina phaseolina, the Causal Agent of Charcoal Rot of Soybean in Argentina

Marco Masi et al.

Summary: Two new penta- and tetrasubstituted cyclopentenones, along with guignardone A, were isolated from Macrophomina phaseolina cultures. These compounds exhibited phytotoxic activity when tested on a nonhost plant, but showed no phytotoxicity or antifungal activity on the host plant soybean and its fungal pathogens. The structures and configurations of the compounds were determined using spectroscopic and chemical methods.

Total Synthesis of the Meroterpenoid Manginoid A as Fueled by a Challenging Pinacol Coupling and Bicycle-forming Etherification

Yu-An Zhang et al.

Summary: The study demonstrated the synthesis of manginoid compounds through a combination of challenging chemical reactions, providing insights for the synthesis of other natural products. The success of the key reactions in the synthesis of manginoids suggests a potential roadmap for accessing related compounds in the future.

Terpene-Shikimate conjugated meroterpenoids from the endophytic fungus Guignardia mangiferae

Keliang Chen et al.

Summary: Nine undescribed shikimate-conjugated meroterpenes, along with nine known compounds, were isolated from solid cultures of the fungus Guignardia mangiferae. The structures of the undescribed compounds were characterized by NMR, HRESIMS, and X-ray crystallography, with some showing inhibitory effects on nitric oxide production.

Enantioselective Total Syntheses of Manginoids A and C and Guignardones A and C

Yan Zong et al.

Summary: An enantioselective synthetic approach for preparing manginoids and guignardones, two types of biogenetically related meroterpenoids, is described in this study. The bioinspired and divergent synthesis involves an oxidative 1,3-dicarbonyl radical-initiated cyclization and cyclodehydration of a common precursor to forge the central ring of the manginoids and guignardones. Key synthetic steps include silica-gel-promoted semipinacol rearrangement and the Suzuki-Miyaura reaction of vinyl bromide for fragment coupling, enabling the asymmetric syntheses of four fungal meroterpenoids from commercially available materials.

The chemistry and biology of fungal meroterpenoids (2009-2019)

Minghua Jiang et al.

Summary: Fungal meroterpenoids are secondary metabolites with diverse chemical structures and potential bioactivities, classified into four categories mainly consisting of polyketide-terpenoids and shikimate-terpenoids. Basidiomycota are major producers of meroterpenoids, with genera like Ganoderma, Penicillium, Aspergillus, and Stachybotrys being dominant. Around 56% of meroterpenoids exhibit significant bioactivities, and some have been developed into clinically used drugs, indicating their potential in drug discovery.
