Biosynthesis of the Red Algal Diterpene Peyssonnosol in Bacteria

open access: yesAngewandte Chemie International Edition, EarlyView.
Two terpene synthases derived from Anaerolineae bacteria catalyse the biosynthesis of peyssonnosene‐type diterpenes from red algae. Site‐directed mutagenesis enabled a partial functional switch, resulting in the formation of additional byproducts. The intricate cyclisation mechanisms were investigated through isotopic labelling experiments and density ...

Tunable Endo/Exo Selectivity in Direct Catalytic Asymmetric 1,3‐Dipolar Cycloadditions with Polyfunctional Lewis Acid / Azolium–Aryloxide Catalysts

open access: yesAngewandte Chemie International Edition, EarlyView.
A novel concept for catalytic asymmetric 1,3‐dipolar cycloadditions with iminoesters employs modular polyfunctional Lewis acid/azolium‐aryloxide betaine catalysts, controlling endo‐ and exo‐selectivity through adjustments of metal center, azolium, and sterics.
