one-component organocatalyst for the atom-economic transformation of epoxides to oxazolidinones under microwave irradiation. Integrating a positively charged center into phenols over a modular one-step preparation gives rise to a bifunctional system with improved acidity and activity, competent in rapid assembly of epoxides and isocyanates under microwave irradiation in a short reaction time (20–60 min)

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

The reaction between acid amides and aryl glycidyl ethers was carried out using tertiary amine as the catalyst. 2-Oxazolidone derivatives were obtained by the reaction of trichloroacetanilide or trifluoroacetanilide with aryl glycidyl ether. Acyl migration occurred in the reaction of acetanilide with phenyl glycidyl ether.

A facile and efficient addition of isocyanates with epoxides in the presence of MgI2 etherate was reported in good yields. The corresponding 2-oxazolidinone could be easily converted into 1,2,3-triazole-oxazolidinone by click reaction in excellent yield.
