 Recent advances in the chemistry of  1,3-oxaselenolanes and 1,3-oxaselenoles  have significantly expanded the landscape of selenium-containing heterocycles in modern organic synthesis. These five-membered rings, incorporating both oxygen and selenium atoms, exhibit unique electronic and redox properties compared to their sulfur and oxygen analogues. In recent years, chemists have developed efficient synthetic strategies including transition-metal catalysis, electrophilic cyclization, and green chemistry approaches that improve yield, selectivity, and functional group tolerance. Such methodologies have made these previously less-explored scaffolds more accessible for structural diversification and mechanistic studies. The fused system benzo[d][1,3]oxaselenoles has attracted particular attention due to its enhanced stability and extended π-conjugation. Modern research highlights innovative annulation reactions, intramolecular cyclizations, and cascade processes that allow...

Mitochondrial transcription plays a crucial role in cellular energy production, as mitochondria contain their own DNA and transcriptional machinery. Traditionally, studying mitochondrial RNA synthesis in vitro relied on radioactive labeling techniques, which posed safety concerns, disposal challenges, and regulatory limitations. ⚠️🧪 Recent advances now offer a safer and more efficient alternative through click-chemistry–based detection methods, eliminating the need for hazardous radioactive isotopes while maintaining high sensitivity and accuracy. 🔬💡 Click chemistry enables the incorporation of modified nucleotides into newly synthesized mitochondrial RNA. These modified molecules contain bioorthogonal functional groups that can react selectively with fluorescent probes under mild conditions. The result is a rapid, highly specific labeling process that allows researchers to visualize and quantify transcription products using fluorescence instead of radiation. This approach enhances ...
