Synthesis of Novel Dihydropyridine‐Iminium Salts Containing a Selenazine Core
Asian Journal of Organic Chemistry, Volume 14, Issue 10, October 2025.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 ...
