Porcine Liver Esterase‐Catalyzed Dynamic Kinetic Resolution of a Lactone‐Bridged Biaryl: Impact of Organic Cosolvents on Enantioselectivity

European Journal of Organic Chemistry, EarlyView.
A stereolabile lactone‐bridged biaryl enables dynamic kinetic resolution to provide a conformationally stable ring‐opened biaryl. A significant positive effect of water‐immiscible organic cosolvents on the enantioselectivity in a reaction catalyzed by porcine liver esterase has been discovered for the first time.

Memory of Chirality in Radical Addition–Translocation–Cyclization Cascades

Helvetica Chimica Acta, EarlyView.
Radical addition–translocation–cyclization cascades of chiral alkynes show striking memory of chirality (MoC), with strong retention of configuration when fast, polarity favored cyclization are involved. The most effective system employs a highly electron‐poor pentafluorobenzenesulfonyl group.

Catechol‐Containing Poly(2‐isopropyl‐2‐oxazoline): Synthesis and Thermoresponsive Behavior in Aqueous Salt Solutions

Macromolecular Rapid Communications, EarlyView.
Polymers carrying catechol groups are interesting mussel‐inspired materials for wet adhesion applications or metal ion complexation for wastewater treatment. Here, catechol‐containing poly(2‐isopropyl‐2‐oxazoline)s were synthesized via microwave‐assisted cationic (co)polymerization and examined with regard to their thermoresponsive LCST behavior in ...

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Living Coordination (Co)Polymerization of Norbornene Derivatives by Using Nickel Catalysts Derived From Bis(1,5‐Cyclooctadiene)nickel(0) and 2,6‐Dihydroxybenzoic Acid

Journal of Polymer Science, EarlyView.
The living coordination polymerization of norbornene is achieved using a nickel catalyst derived from Ni(cod)2 and 2,6‐dihydroxybenzoic acid with trityl borate as cocatalyst to produce poly(norbornene) with controllable molecular weights and narrow polydispersity.

Boron‐10 carriers and their applications in boron neutron capture therapy

Precision Radiation Oncology, EarlyView.
Summary of different types of boron drugs. Abstract Boron neutron capture therapy (BNCT) has emerged as a promising therapeutic modality in cancer treatment, demonstrating the ability to selectively eliminate cancer cells through the 10B(n,α)7Li nuclear reaction with minimal side effects on normal tissues.

Synthesis of Amorphous‐Crystalline Mixture Boron Nitride for Balanced Resistive Switching Operation

Small, EarlyView.
An amorphous–crystalline mixture BN (acm‐BN) is synthesized through low‐pressure chemical vapor deposition, achieving balanced resistive switching with low SET voltage and stable RESET. High‐resolution transmission electron microscopy reveals that BN films are fully amorphous at 930 °C, a mixed amorphous–crystalline phase is achieved at 990 °C.

Increasing the Lewis Acidity of Pyramidal Boranes: Cationic 9‐Bora‐1‐Azatriptycenes as Strong Boron Lewis Superacids

ChemistryEurope
Bora‐azatriptycenes have been synthesized and used as geminal pyridine–boranes pairs, which exhibit unusual binding modes with weakly coordinating anions, to unique aza‐triptycene/bora‐triptycene Lewis adducts, and to bis‐triptycenes dimers with ...
