Article Abstract

A biomimetic route to farnesyl pyrophosphate and dimethyl orsellinic acid (DMOA)-derived meroterpenoid scaffolds has yet to be reported despite great interest from the chemistry and biomedical research communities. A concise synthetic route with the potential to access DMOA-derived meroterpenoids is highly desirable to create a library of related compounds. Herein, we report novel dearomatization methodology followed by polyene cyclization to access DMOA-derived meroterpenoid frameworks in six steps from commercially available starting materials. Furthermore, several farnesyl alkene substrates were used to generate structurally novel, DMOA-derived meroterpenoid derivatives. DFT calculations combined with experimentation provided a rationale for the observed thermodynamic distribution of polycyclization products.

A new 18,22-cyclosterol, aspersteroline A (1), and a new DMOA-derived meroterpenoid, asperterpene O (2), along with three known compounds (3 - 5), namely mer-NF8054X (3), terretonin D (4), and asperterpene J (5), were isolated from the soil-derived Aspergillus versicolor QC812. The structures of new compounds were established based on widespread spectrographic methods, mainly including 1D & 2D NMR and HRESIMS analyses, and the absolute configurations were further confirmed by comparison of calculated and experimental electronic circular dichroism (ECD) curves. The cytotoxicity of isolates was evaluated on five human tumor cell lines, 1 and 3 showed moderate cytotoxic activities against HL-60.

The synthesis of complex natural products requires efficient control over chemoselectivity, stereoselectivity, and regioselectivity. Berkeleyacetals, a subfamily of 3,5-dimethylorsellinic acid (DMOA)-derived meroterpenoids, pose substantial synthetic challenges due to their densely functionalized and highly oxidized architectures, which have constrained synthetic efforts. Here, we present the first total synthesis of this class of DMOA-derived meroterpenoids, specifically (+)-berkeleyacetal D and (+)-peniciacetal I.

Two undescribed 3,5-dimethylorsellinic acid (DMOA) derived meroterpenoids, namely pancosterpenoids A (1) and B (2), were discovered from the EtOAc extract of the deep-sea sediment-derived fungus Penicillium pancosmium A6A. The gross structures were established by detailed analysis of the spectroscopic data (NMR and HRESIMS spectra), while their absolute configurations were resolved by comparing the experimental and calculated ECD data as well as X-ray single crystal diffraction analysis. Pancosterpenoid A (1) was the first representative of DMOA-derived meroterpenoids possessing a 6/6/6/5/5 pentacyclic system, while pancosterpenoid B (2) belongs to a class of rare 13-nor-citreohybridone meroterpenoids.

Fungal meroterpenoids are diverse structurally intriguing molecules with various biological properties. One large group within this compound class is derived from the aromatic precursor 3,5-dimethylorsellinic acid (DMOA). In this study, we constructed engineered metabolic pathways in the fungus to expand the molecular diversity of meroterpenoids.
