A new protocol to prepare 2‐aryl‐3‐(arylselanyl)imidazo[1,2‐a]pyridines under blue light irradiation, using benzeneseleninic acid derivatives as selenium source, is described. The experimental design approach (DoE) was used to establish the best reaction conditions, which delivered fourteen derivatives in moderate to good yields (23%–75%) using water ...

Reactivity of a Methylene‐Bridged 1,3‐Bis(germylene) in Dynamic Equilibrium with Its Dimer
We report the properties and reactivity of an unprecedented methylene‐bridged 1,3‐bis(germylene) derivative. In the solid state, the 1,3‐bis(germylene) derivative undergoes dimerization to afford a 1,2,4,5‐tetragermacyclohexa‐1,4‐diene (Ge4CHD) derivative.

Synthesis of Novel Dihydropyridine‐Iminium Salts Containing a Selenazine Core
An efficient method to develop novel dihydropyrido[3,2‐e][1,3]selenazines iminium salts. A comparative study of the key reagent selenourea towards thiourea and urea was carried out to assess the contribution of chalcogen to the pathway. DFT (density functional theory) calculations have predicted the optimized minimum energy structure for the hybrid ...

Nanostructured Biomaterial‐Based Approaches to Support Induced Pluripotent Stem Cell Differentiation
Induced pluripotent stem cells (iPSCs), reprogrammed from adult somatic cells, represent an innovative approach for regenerative medicine and biomedical applications. This review highlights the importance of nanostructured biomaterials, utilized as delivery systems or scaffolds, in supporting iPSC differentiation and fate through structural and ...
