Abstract
A one-pot approach to substituted 1,2,4-triazolo[4,3-]pyridines has been developed that is based on a KI-catalyzed oxidative cyclization of α-keto acids and 2-hydrazinopyridines. This transition-metal-free procedure was highly efficient and shows good economical and environmental advantages.
摘要
已开发出一种一锅法制备取代的1,2,4-三唑并[4,3-b]吡啶的方法，该方法基于碘化钾催化的α-酮酸与2-肼基吡啶的氧化环化反应。这种无过渡金属的方法效率高，具有良好的经济和环境优势。
