Pharmaceuticals Made with Hydrogen: A Sustainable and Efficient Approach Using Flow Synthesis

Chemistry – A European Journal, EarlyView.
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.

AgBF4‐Induced Site‐Selective Synthesis of 4‐Sulfonylindoles in Au‐Catalyzed Cyclization‐Sulfonyl Migration Reactions

Chemistry – A European Journal, EarlyView.
Site‐selective synthesis 4‐suflonylindoles was achieved by a cyclization‐rearrangement strategy by π‐Lewis acidic gold catalysts and the aid of silver cocatalyst. Particularly, the use of 3 equivalents of AgBF4 to SPhosAuCl is crucial for C4‐selective migration of the sulfonyl group.

It's a Gas: Bioconjugation With Vapor‐Phase Reagents

Chemistry – A European Journal, EarlyView.
Gaseous reagents are an emerging class of bioconjugation reagents that can offer alternative selectivity paradigms for the construction of precise bioconjugates. A variety of both inert and highly reactive gases have recently been developed for bioconjugation use.

Dual Ligand‐Enabled Nondirected C─H Olefination of (Hetero)Arenes for the Synthesis of Clickable Derivatives

Chemistry – A European Journal, EarlyView.
We report an efficient method for late‐stage installation of “clickable” alkyne groups into diverse (hetero)arenes. Using a dual‐ligand palladium catalyst that combines an NASA ligand with an N‐heterocycle, an acrylate unit bearing a terminal alkyne can be introduced via nondirected C─H activation.

Enantioselectivity in Transition Metal Catalyzed Propargylic Substitution Reactions: A Theoretical Perspective

Chemistry – A European Journal, EarlyView.
Recent theoretical efforts to elucidate the origin of enantioselectivity in transition metal‐catalyzed propargylic substitution reactions are highlighted in this review. ABSTRACT In recent years, asymmetric catalytic propargylic substitution reactions have undergone remarkable development, enabling the construction of chiral carbon centers adjacent to ...
