Three‐component reaction of epoxides, amines, and dimethyl carbonate catalyzed by rare‐earth metal amides has been developed to synthesize oxazolidinones. 47 examples of 3,5‐disubstituted oxazolidinones were prepared in 13–97 % yields. This is a simple and most practical method which employs easily available substrates and catalysts, and is applicable to a wide range of aromatic and aliphatic amines
已开发了稀土金属酰胺催化的环氧化物,胺和碳酸二甲酯的三组分反应,以合成恶唑烷酮。制备了47个3,5-二取代的恶唑烷酮实例,产率为13–97%。这是一种简单且最实用的方法,它使用易于获得的底物和催化剂,适用于各种芳族和脂族胺以及单取代的环氧化物。二取代的环氧化物的范围相当有限,这需要进一步研究。初步的机理研究揭示了通过β-氨基醇或酰胺中间体产生的两种可能的反应途径。
