Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Sustainable Synthesis of 4,7‐Dihydro‐4,7‐ethano‐2H‐isoindoles—Key Building Blocks to Benzoporphyrins

Chemistry – A European Journal, EarlyView.
A facile and sustainable route to isoindole derivatives—key benzoporphyrin precursors—brings high‐ and low‐symmetry benzoporphyrins closer to practical application. ABSTRACT Benzoporphyrins, π extended porphyrin analogues, exhibit remarkable potential for optoelectronic and theragnostic applications, yet have remained largely confined to fundamental ...

Mechanochemical Amidation Mediated by 1,1’‐Oxalyldiimidazole for the Synthesis of Agrochemicals

Chemistry – A European Journal, EarlyView.
Mechanochemical amidation using 1,1'‐oxalyldiimidazole (ODI) overcomes limitations of 1,1’‐carbonyl diimidazole (CDI) as coupling agent by enabling the efficient mechanochemical synthesis of three marketed agrochemicals from deactivated carboxylic acids.

Embryonic cerebrospinal fluid pressure in fetal mice in utero: External factors pressurize the intraventricular space

Developmental Dynamics, EarlyView.
Abstract Background Previous experiments inducing leakage of embryonic cerebrospinal fluid (CSF) suggest the necessity of intraventricular CSF pressure (PCSF) for brain morphogenesis. Nevertheless, how embryonic PCSF occurs is unclear, especially in utero. Results Using a Landis water manometer, we measured PCSF in fetal mice isolated from the amniotic
