P‐Stereogenic Phosphines via Mn(I)‐Catalyzed Asymmetric Hydrophosphination of Vinyl Sulfones: A Case of Solvent‐Induced Stereoinversion

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A new strategy for synthesis of P‐chiral phosphines via manganese‐catalyzed enantioselective hydrophosphination was established. The solvent like iPrOH was found to be able to tune the enantioselectivity of the product, thus providing both enantiomers of P(III)‐stereogenic compounds with a single (Rc, Sp)‐Clarke Mn(I) complex catalyst. In this work, we

Domino Synthesis of Functionalized Cyclic Acetals From Organic Carbonates

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Cyclic carbonates equipped with acrylic functional groups are shown to undergo a domino process in the presence of a suitable alkoxide to deliver novel types of decorated cyclic acetals. The developed protocol combines practical conditions and a wide scope and features a new reactivity modus for these carbon dioxide‐derived heterocyclic precursors.

Therapeutic Antibodies for Mosquito‐Borne Orthoflavivirus Infections: Discovery, Engineering Approaches, and Advances in mRNA‐Based Delivery Systems

open access: yesAdvanced Therapeutics, EarlyView.
This review explores how antibody engineering and display technologies are driving therapeutic advances against mosquito‐borne orthoflaviviruses such as Zika, dengue, and yellow fever viruses. It highlights diverse neutralizing targets on the envelope protein, including the conserved fusion loop, and discusses how Fc engineering, rational antigen ...

Hepatitis E Virus ORF1 Polyprotein Harbors a Pocket‐Like Cavity That Is Vital for Virus Replication and Represents a Novel Antiviral Target

open access: yesAdvanced Science, EarlyView.
Within the hepatitis E virus (HEV) ORF1 polyprotein, the X domain interacts with viral RNA‐dependent RNA polymerase (RdRp), forming a functional “pocket‐like” cavity (PC) that is crucial for viral replication. Structure‐based screening, surface plasmon resonance (SPR) assays, and HEV model validation collectively identify saikosaponin D and ...
