Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols

Angewandte Chemie, EarlyView.
Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Nonnative Thiol and Aniline Methylation, Including Enantioselective Dithiol Desymmetrization, by Multicomponent Cobamide‐Dependent Methyltransferases Using Unactivated Methyl Donors

Angewandte Chemie, EarlyView.
Mixed MtaABC/MtgABC methyltransferase systems were developed for non‐native thiol and aniline methylation using the unactivated methyl donors methanol and glycine betaine. The platform enabled site‐selective and enantioselective methylation with turnover number up to 6000, representing the first enantioselective non‐native catalysis by cobamide ...

Spin‐Polarized Interfaces Redirect CO2 Reduction From CO to Formate

Angewandte Chemie, EarlyView.
The chiral electrocatalyst exploits the CISS effect to establish a spin‐polarized interface that selectively promotes formate production during CO2 reduction while effectively suppressing the competing hydrogen evolution. ABSTRACT Achieving high product selectivity in electrocatalytic carbon dioxide reduction (CO2RR) remains a critical challenge due to

1‐Azabicyclo[1.1.0]butanes (ABBs) on the Map: Mechanistic Pathways for Catalytic Ring Opening and Functionalizations

Angewandte Chemie, EarlyView.
Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Counterion Dynamics in Chiral Supramolecular Polymerization

Angewandte Chemie, EarlyView.
A single counterion acts as a dynamic structural element directing pathway‐dependent supramolecular polymerization. Subtle counterion repositioning governs molecular packing, aggregate morphology, supramolecular chirality, and asymmetry amplification. ABSTRACT Counterions have been studied in a broad range of chemical and biological systems, and their ...

One‐End‐Truncated Au52 and Au70 Quantum Rods: High‐Quantum‐Yield NIR‐II Emitters With Aspect‐Ratio‐Dominated Photophysics

Angewandte Chemie, EarlyView.
Two nanoclusters, Au52(PET)38 and Au70(PET)50, where PET = 2‐phenylethanethiolate, are isolated, which constitute a series of one‐end‐truncated kernel topologies. Both Au52 and Au70 exhibit NIR‐II absorption at 1032 and 1275 nm and nanosecond fluorescence at 1100 and 1360 nm, respectively, with high quantum yields (20.9% for Au52 and 14.8% for Au70 ...
