Eine Universelle Nukleosid‐zu‐Nukleosid‐5′‐triphosphat‐Enzymkaskade angetrieben durch Polyphosphat

Angewandte Chemie, EarlyView.
Nukleosid‐5′‐Triphosphate (NTPs) sind wichtige Bausteine für Nukleinsäuren. Ihre chemische Synthese ist aufgrund der geringen Ausbeute der 5′‐Triphosphorylierungsreaktion nur wenig effizient. Wir stellen hier eine universelle, durch Polyphosphat angetriebene Zwei‐Enzym‐Kaskade vor, die eine direkte Phosphorylierung von Nukleosiden zu NTPs ermöglicht ...

Coordination‐Driven Direct C─H Metalation of N‐Heterocycles With a Superbasic Co(II) Amide Co(TMP)2

Angewandte Chemie, EarlyView.
By enabling regioselectivities that are inaccessible with conventional bases, this study introduces a Co(II) amide platform for the deprotonative C─H metalation of sensitive N‐heterocycles. Subsequent interception of the resulting Co(II) intermediates with external oxidants affords a family of sterically congested, TMP‐substituted heterocycles via C─N ...

Metal‐Free Active Template: A Straightforward Route to 4‐Aminopyridinium‐Based Rotaxane Molecular Shuttles

Angewandte Chemie, EarlyView.
Leigh's metal‐free active template‐based SNAr of an amine on halogenopyridiniums, in the presence of a crown ether, successfully afforded 4‐aminopyridinium‐containing rotaxanes. Further molecular machinery was carried out by deprotonation‐then‐carbamoylation of the conjugated amino moiety.

Glycine‐Induced Unique Crystal Packing of Octacyanidetungstates With Strong Intermolecular Antiferromagnetic Interaction, Near‐Infrared Emission, and Second Harmonic Generation

Angewandte Chemie, EarlyView.
Glycine molecules induce a unique crystal packing into a supramolecular one‐dimensional columnar structure of octacyanidotungstates, which exhibits exceptionally strong antiferromagnetic superexchange interactions of J = −42.41(2) K between adjacent octacyanidotungstate units.
