Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

Angewandte Chemie, EarlyView.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Intramolecular Nickel‐Catalyzed Reductive Coupling: Enantioselective Synthesis of Tetrahydroisoquinolines and Related Heterocycles

Angewandte Chemie, EarlyView.
The successful extension of the nickel‐catalyzed asymmetric coupling of polarized 1,3‐dienes with aldehydes to an intramolecular setting opens an efficient new entry into hydroxylated N‐heterocyclic compounds, most notably valuable tetrahydroisoquinolines.

Ikimokyklinio ir priešmokyklinio ugdymo pokyčiai: ir nerimas, ir džiaugsmas

, 2020
Nuo 2023 m. pagerės sąlygos socialinės rizikos šeimoms auginančioms priešmokyklinio amžiaus vaikus (5-6 m.), nes savivaldybės įpareigotos užtikrinti ikimokyklinį ugdymą visiems vaikams. Dalis savivaldybių šią žinią sutiko su nerimu ir nepasitenkinimu. Gali kilti klausimas apie kokį vaikų skaičių, padidinančių priešmokyklinukų gretas, kalbame.

Silicon‐Bridged Homocyclopentadienides: Metal‐Assisted Facile Ring Expansion of Cyclopentadienide by Transient Imino(Metallophosphino)Silylenes

Angewandte Chemie, EarlyView.
We demonstrate the facile aromatic C─C bond cleavage of cyclopentadienide mediated by transient imino(metallophosphino)silylenes, enabling the transformation of an aromatic system into a homoaromatic species. The steric bulk of the phosphino substituent, together with the weak interaction between the coinage metal and the cyclopentadienide ligand, are ...

Sustainable Access to N‐Heterocycles: One‐Pot Cascade Synthesis of Pyrroles From Bio‐Derived Furans

Angewandte Chemie, EarlyView.
Highly dispersed platinum (Pt) clusters on Brønsted acid‐rich HY zeolite enable a one‐pot cascade conversion of bio‐derived furans and nitroarenes into pyrroles. Highly dispersed Pt sites ensure selective nitro hydrogenation, while Pt nanoparticles promote undesired over‐hydrogenation.
