Abstract
Herein we report the first enantioselective total synthesis of 3,5-dimethylorsellinic acid-derived meroterpenoids (-)-berkeleyone A and its five congeners ((-)-preaustinoids A, A1, B, B1, and B2) in 12-15 steps, starting from commercially available 2,4,6-trihydroxybenzoic acid hydrate. Based upon the recognition of latent symmetry within D-ring, our convergent synthesis features two critical reactions: 1) a symmetry-breaking, diastereoselective dearomative alkylation to assemble the entire carbon core, and 2) a Sc(OTf)3 -mediated sequential Krapcho dealkoxycarbonylation/carbonyl α-tert-alkylation to forge the intricate bicyclo[3.3.1]nonane framework. We also conducted our preliminary biomimetic investigations and uncovered a series of rearrangements (α-ketol, α-hydroxyl-β-diketone, etc.) responsible for the biomimetic diversification of (-)-berkeleyone A into its five preaustinoid congeners.

Abstract
Fungal meroterpenoids are a diverse group of hybrid natural products with impressive structural complexity and high potential as drug candidates. In this work, we evaluate the promiscuity of the early structure diversity-generating step in fungal meroterpenoid biosynthetic pathways: the multibond-forming polyene cyclizations catalyzed by the yet poorly understood family of fungal meroterpenoid cyclases. In total, 12 unnatural meroterpenoids were accessed chemoenzymatically using synthetic substrates. Their complex structures were determined by 2D NMR studies as well as crystalline-sponge-based X-ray diffraction analyses. The results obtained revealed a high degree of enzyme promiscuity and experimental results which together with quantum chemical calculations provided a deeper insight into the catalytic activity of this new family of non-canonical, terpene cyclases. The knowledge obtained paves the way to design and engineer artificial pathways towards second generation meroterpenoids with valuable bioactivities based on combinatorial biosynthetic strategies.

Abstract
The crystalline sponge (CS) method allows structural elucidation of a target compound (guest) in solution by single crystal X-ray diffraction through trapping the guest into the CS framework. In principle, the CS method is inapplicable to reactive compounds that break the CS framework, such as acidic, basic, or nucleophilic ones. Here, a solution to this problem is disclosed wherein an ion pair of the guest compound is formed during the guest-soaking step by adding a suitable reagent. The ion pair can be observed and does not damage the CS framework. Using the developed method, amino, guanidino, and amidino compounds have been successfully analyzed as ion pairs with sulfonic acids. Practical utility has been shown because the absolute configurations of optically resolved amine derivatives were revealed with only a few micrograms. This demonstrates that the ion-pair-soaking method is simple and expands the range of compounds applicable to the CS method.
