Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

open access: yesAngewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Patient‐Personalized Membrane‐Coated Magnetic Nanovectors: Probing the Biomimetic Interface for Targeted Tumor Theranostics

open access: yesAdvanced NanoBiomed Research, EarlyView.
This study presents a label‐free spectroscopic platform to evaluate membrane protein conformation on patient‐derived glioblastoma cell membrane‐coated magnetic nanovectors. This work demonstrates that preserving membrane protein integrity during nanoparticle fabrication enhances homotypic tumor targeting and reduces hard protein corona formation ...

An Alkali Amide Approach to Triphosphabenzenes

open access: yesAngewandte Chemie, EarlyView.
Alkali metal amides offer a simple route to phosphorus aromatics. LiNMe2 catalyzes [2+2+2] cyclotrimerization of a phosphaalkyne, while tetrahydrofuran (THF) stabilizes a λ4‐triphosphabenzene anion intermediate. Using KN(SiMe3)2 switches reactivity to arene C(sp3)─H activation, giving benzylated λ4‐triphosphabenzenes and rare λ5‐triphosphabenzenes ...

Biomimetic Nanomedicine for Aging‐Impaired Bone Regeneration: From Microenvironmental Dysfunction to Precision Therapeutics

open access: yesAdvanced NanoBiomed Research, EarlyView.
Aging disrupts the cellular, immune, vascular, and neural processes required for bone regeneration. This review connects these pathological barriers with biomimetic nanomedicine design, highlighting strategies for cellular rejuvenation, immune modulation, vascular regeneration, and neuro–bone coupling.

Macrocyclization of ω‐Isocyano Aldehydes

open access: yesAngewandte Chemie, EarlyView.
The ω‐isocyano aldehydes readily undergo cyclization to afford α‐acyloxy, α‐hydroxy, α‐acetamido, and α‐keto macrolactams, as well as tetrazole‐fused macrocycles, via C(sp3)─C(sp2) bond formation, providing access to diverse α‐functionalized medium‐sized lactams and macrolactams. ABSTRACT Medium‐sized rings and macrocycles constitute a privileged class

Sequence‐Controlled Helical Ladder Polymers: Impact of Stereochemical Sequence on Helical Geometry and Chiral Recognition

open access: yesAngewandte Chemie, EarlyView.
Nature programs distinct secondary structures and functions through subtle stereochemical differences, as exemplified by amylose and cellulose. Translating this principle into synthetic ladder polymers, stereochemical sequence control gives rise to diastereomeric coil‐ and ribbon‐type helices with complementary chiral recognition, demonstrating ...
