The absolute configuration of isochamigrene: New insights into the cyclisation mechanism of trichodiene synthase

Isochamigrene, a side product of the trichodiene synthase, which is a key enzyme from the biosynthesis of the trichothecene mycotoxins from Fusarium spp., was enantioselectively synthesised and compared to the natural product from Fusarium sporotrichioides. As a result, its absolute configuration was assigned to (S)-isochamigrene. Implications for the recently extensively discussed cyclisation mechanism towards trichodiene and its side products are discussed.

Design and Synthesis of the Active Site Environment in Zeolite Catalysts for Selectively Manipulating Mechanistic Pathways

By combining kinetics and theoretical calculations, we show here the benefits of going beyond the concept of static localized and defined active sites on solid catalysts, into a system that globally and dynamically considers the active site located in an
