Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis

open access: yesChemistryEurope, EarlyView.
This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex

Synthetic Study on Bicyclic Pyranonaphthoquinone Natural Products: Construction of the Dioxabicyclo[3.3.1]nonene Motif

open access: yesChemistryEurope, EarlyView.
The method for the stereoselective formation of dioxabicyclo[3.3.1]nonene structure has been developed. The intriguing bicyclic skeleton is embedded in hybrid‐type pyranonaphthoquinone natural products, e.g., glenthamine Treatment of nanaomycin D and naphthol with Na2HPO4 in DMSO and water affords the bicyclic compound in good yield.

Effect of Chalcogen Interaction on the Structure of Methine‐Bridged Trichalcogenophenes

open access: yesChemistry – A European Journal, EarlyView.
The stereochemistry of methine‐bridged trichalcogenophenes was elucidated through comprehensive structural analyses. Trithiophene showed a strong preference for the ZZ configuration, whereas its trifuran analog exhibited a near‐statistical distribution of geometric isomers. X‐ray crystallography and computational studies revealed that intramolecular S··

Photocatalytic Oxidation of Alcohols with Organic Dyes: From Homogeneous Systems to Sensitized Materials

open access: yesChemistry – A European Journal, EarlyView.
We discuss the developments in the light‐driven oxidation of alcohols with PC. We report cases where the homogeneous systems can be interfaced with electrochemical tools or adapted in flow and where the PC are integrated in sensitized materials. Abstract The oxidation of alcohols retains an enormous importance in industry and in synthetic organic ...
