开发了一种基于经济且易于获得的氰尿酸的有机催化系统，用于在大气压二氧化碳下由炔丙胺和2-氨基苯甲腈合成2-恶唑烷酮和喹唑啉-2,4(1H,3H)-二酮。值得注意的是，空气中低浓度的二氧化碳无需外部碱即可以优异的产率直接转化为 2-恶唑烷酮。通过原位 FTIR 光谱的机理研究，三聚氰酸被证明是一种有效的二氧化碳固定催化剂。
A organocatalytic system based on economical and readily available cyanuric acid has been developed for the synthesis of 2‐oxazolidinones and quinazoline‐2,4(1H,3H)‐diones from propargylamines and 2‐aminobenzonitriles under atmospheric pressure carbon dioxide. Notably, a low concentration of carbon dioxide in air was directly converted into 2‐oxazolidinone in excellent yields without an external base. Through mechanistic investigation by in situ FTIR spectroscopy, cyanuric acid was demonstrated to be an efficient catalyst for carbon dioxide fixation.
