Computational Study of Ignored Pericyclic Reactions: Rearrangements of 1,2‐Bis(Diazo)Alkanes to 1,2,3,4‐Tetrazines and Subsequent Fragmentations

Angewandte Chemie, EarlyView.
DFT calculations of the 8π‐electrocyclization of 1,2‐bis(diazo)alkanes and of other bis‐1,3‐dipoles reveal that this process can establish a so far ignored route to heterocycles such as 1,2,3,4‐tetrazines. Alternative reaction channels via carbenes or nitrenes leading to fragmentation products are discussed.

From Pharmacophore to Warhead: NAD+‐Targeting Triazoles as Mechanism‐Based Sirtuin Inhibitors

Angewandte Chemie, EarlyView.
We report “Sirtuin Trapping Ligands” (SirTraps), mechanism‐based 1,2,3‐triazole inhibitors that hijack sirtuin (SIRT) catalysis to form covalent triazolium– or triazole–ADP‐ribose (ADPR) adducts from NAD+. These trapped intermediates stall the enzyme in an inactive state, providing a biocompatible alternative to thiocarbonyl inhibitors and a blueprint ...

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

Advanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.
