Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis
Chemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.We demonstrate a sustainable strategy for pharmaceutical manufacturing by combining hydrogen, heterogeneous catalysis, and continuous flow synthesis. The development of novel catalysts and their application in a multi‐step synthesis of donepezil enabled a highly productive process with no intermediate purification.

European Journal of Organic Chemistry, Volume 29, Issue 26, 13 July 2026.Asymmetric synthesis of antimalarial yingzhaosu C was achieved in 4–5 steps by asymmetric Grignard synthesis of (R)‐gossonorol followed by novel enantiospecific hydroperoxidation. We report a concise asymmetric synthesis of antimalarial yingzhaosu C in 59% ee.

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 4, July/August 2026.ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.The first microwave‐assistance‐free heterogeneous catalytic upcycling of polyoxymethylene (POM) into valuable cyclic acetals is achieved with a reusable proton‐exchanged montmorillonite (H‐Mont) catalyst. Combining interlayer accessibility with strong acidity, H‐Mont enables efficient, regenerable, and versatile transformations with potentially biomass‐
