Recyclable Dynamic Covalent Networks Derived from Isocyanate Chemistry: The Critical Role of Electronic and Steric Effects in Reversibility

open access: yesChemSusChem, Volume 18, Issue 13, July 1, 2025.
The emergence of dynamic covalent networks, featuring dynamic covalent bonds formed through isocyanate‐involved chemistry, aims to substitute conventional, non‐recyclable polyurethanes and polyureas. The review examines the reversibility of these dynamic bonds and the relevant polymer networks from the lens of electronic and steric influences.The ...

Aminoisothiazolamides, a new class of potent inhibitors of lysyl‐tRNA synthetase

open access: yesPest Management Science, Volume 81, Issue 7, Page 3956-3983, July 2025.
The present work covers a series of novel herbicidal lead structures that possess an aminoisothiazolamide scaffold as a structural key feature. Lysyl‐tRNA synthetase 1 (KRS1) was identified as the biochemical mode‐of‐action. Based on optimized and tailored synthetic approaches, a broader SAR study was carried out delivering some lead structures that ...

Nachweis von 4-Homocubyl-Carbenium-Ionen als reaktive Zwischenstufen [PDF]

open access: yes, 1983
Bei der Thermolyse von N-(4-Homocubyl)-N-nitrosoacetamid (9) und bei der Solvolyse von 4-Homocubylbromid (5) in Hexafluor-2-propanol entsteht 4-(Hexafluorisopropoxy)homocuban (6) als Hauptprodukt. Dies beweist das Auftrete von 4-Homocubyl-Carbenium-Ionen

Intramolecular amidocyclopropanation reactions using diethoxymethyl-functionalised lactams as organozinc carbenoid precursors [PDF]

open access: yes, 2009
Intramolecular amidocyclopropanation reactions of diethoxymethyl-lactams containing a pendant alkene were examined using zinc/TMSCI. With a range of 4-6-membered lactams, bicyclic amidocyclopropanes were obtained with very high diastereoselectivity with ...
