Exploring the reactivity of 2-trichloromethylbenzoxazoles for access to substituted benzoxazoles [PDF]
The reactivity of 2-trichloromethylbenzoxazoles towards various nucleophiles, under metal free or iron-catalyzed conditions, for the synthesis of substituted benzoxazoles is described. These methods allow for selective substitution at either the 2- or 2’-

Abstract While arylazo sulfones have been widely applied as arylating agents, their exploitation for diazenylation reactions has been previously limited to electron‐rich alkenes such as styrenes and silyl enol ethers. Herein we optimized a synthetic one‐pot protocol to access oxazolyl azo compounds via a selective domino ring‐closing/aryldiazenylation ...

The blue fluorescent molecule 2‐phenyl‐naphth[2,3‐d]oxazole (Nzx) exhibits strong emission in both solution and solid states. Such behavior, referred to as solution and solid‐state emission (SSSE), makes Nzx a promising candidate for optoelectronic applications. This study highlights the potential of Nzx for the development of stable and efficient near

Kinetics of Photo-Oxidation of Oxazole and its Substituents by Singlet Oxygen
Oxazole has critical roles not only in heterocycle (bio)chemistry research, but also as the backbone of many active natural and medicinal species. These diverse and specialised functions can be attributed to the unique physicochemical properties of ...
