A general and efficient synthesis of dihydroquinoxalinones has been developed. The reductive cyclization of N‐(o‐nitroaryl)amino esters was performed by using iron and zinc metal under mild conditions in a water/ethyl acetate mixture. The final products were obtained in moderate to high yields and high enantiomeric purity.
已经开发了二氢喹喔啉酮的通用且有效的合成方法。N-(邻-硝基芳基)氨基酯的还原环化反应是在水/乙酸乙酯混合物中,在温和条件下使用铁和锌金属进行的。以中等至高产率和高对映体纯度获得最终产物。
