Access to highly substituted oxazoles by the reaction of α-azidochalcone with potassium thiocyanate
Beilstein Journal of Organic Chemistry, 2020 The reactivity of α-azidochalcones has been explored for the preparation of highly substituted oxazoles via a 2H-azirine intermediate. The azidochalcones, when treated with potassium thiocyanate in the presence of potassium persulfate, lead to 2,4,5 ...

Excimer Formation in Aqueous Solutions of Hosts and Application in Synthesis
ChemPhotoChem, Volume 10, Issue 4, April 2026.This review explores how host‐mediated excimer formation in water, facilitated by supramolecular confinement enhances photochemical synthesis. By improving solubility, local concentrations, and orientational control, these systems can boost efficiency and selectivity in reactions like photocycloadditions and photodimerizations.

Insights into the Electronic Structure of CuII Bound to an Imidazole Analogue of Westiellamide. [PDF]
, 2014 Three synthetic analogues of westiallamide, HL, have previously been synthesized (HL) that have a common backbone (derived from l-valine) with HL but differ in their heterocyclic rings (imidazole, oxazole, thiazole, and oxazoline).
