Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

Advanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Incorporating Heavy Atom Effect onto Molecular Rotors for Realizing Exceptionally Photocatalytic Oxidation Reaction under Low‐Temperature Conditions

Advanced Materials Interfaces, EarlyView.
Here, we reported a series of molecular‐rotor‐based photoactivated oxidase mimics, DAPy‐Xm, in which heavy atom incorporation enhances both ROS generation and cold‐adapted property. Among them, DAPy‐Im enables efficient photo‐oxidation of ergosterol and photocatalytic H2O2 production at low temperature.

Chiral Potassium Brønsted Base‐Catalyzed Stereoselective Synthesis of 1,3‐Diols via a Tandem Allylic Isomerization/Asymmetric Aldol–Tishchenko Reaction

Advanced Synthesis &Catalysis, EarlyView.
Chiral potassium base catalysts featuring 1,1´‐bi‐2‐naphthol‐derived chiral crown ethers as ligands promote a tandem allylic isomerization/asymmetric aldol‐Tishchenko reaction of allylic alcohols and aldehydes. This method provides enantioenriched 1,3‐diols with excellent diastereoselectivity and high enantioselectivity, thereby expanding the synthetic

Efficient Preparation of Homogenous Antibody Conjugates via Glycosite‐Specific Transglycosylation Enabled by Readily Available Glycosyl Donors

Angewandte Chemie, EarlyView.
A streamlined platform for glycosite‐specific antibody conjugation is enabled by LacNAc‐derived cyclic acetal donors, which can be prepared in only two steps and used directly in single‐enzyme Endo S2‐mediated transglycosylation. The platform supports the broad construction of homogeneous gsADCs and gsDACs, with donor 7 producing glycoengineered ...

Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes

Advanced Synthesis &Catalysis, EarlyView.
The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.

Protein Language Model‐Guided Engineering of a 2,3‐Butanediol Dehydrogenase for the Enantioselective Synthesis of Cyclic α‐Hydroxy Ketones

Advanced Science, EarlyView.
A (2R,3R)‐butanediol dehydrogenase from Bacillus subtilis (BsBDH) is engineered for the enantioselective synthesis of 2‐hydroxycyclohexanone. A PASS computational design strategy is proposed to enhance the thermostability of BsBDH. Moreover, ESM‐1v combined with ISM is utilized for enhancing and inverting its stereoselectivity.
