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 ...

Valency‐Controlled Multiphotochromism: Gated Switching and Photoswitchable Lewis Superacidity at Silicon

Angewandte Chemie, EarlyView.
Multiphotochromic switching is controlled by silicon valency in a diarylethene‐based molecular architecture. Lewis base coordination gates electronic communication between the photochromic units, thereby enabling selective access to distinct switching states.

Enantioselective Synthesis of Axially Chiral Diaryl Ethers via Rhodium‐Catalyzed [2 + 2 + 2] Cycloaddition

Angewandte Chemie, EarlyView.
An enantioselective rhodium‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of axially chiral diaryl ethers. Carbonyl coordination ensures high reactivity and regioselectivity, affording products bearing up to four stereogenic axes with good enantio‐ and diastereoselectivity.

Direct Regioselective para‐Fluorination via I(I)/I(III) Catalysis

Angewandte Chemie, EarlyView.
A direct, para‐selective fluorination by I(I)/I(III) catalysis is disclosed that does not require substrate pre‐functionalization. This strategy leverages the Leonard link inherent to phenylpropanoate and phenylpropanamides to promote a spirocyclization/para‐selective sequence. The C3‐side chain maps onto a range of common drug scaffolds and allows the

Enantioselective Synthesis of a New Class of Stable and Functionalized Cyclopentadienes via CuH‐Catalysis

Angewandte Chemie, EarlyView.
Cyclopentadienes (CpHs) are fundamental building blocks with widespread applications in chemistry. However, their inherent acidity and isomeric instability have long limited access to chiral variants in an asymmetric fashion. Here, we introduce a CuH‐catalyzed asymmetric transformation that provides an unprecedented entry into a new class of ...
