Quaternary ammonium salt-catalyzed carboxylative cyclization of propargylic amines with CO2

Quaternary ammonium salt-catalyzed carboxylative cyclization of propargylic amines with CO2
By employing quaternary ammonium salts as catalysts, the carboxylative cyclization of the propargylic amines with CO2 proceeded to afford the corresponding 2-oxazolidinones. In particular, tetra-n-butylammonium fluoride was the most effective catalyst for the reaction, providing a 2-oxazolidinone derivative in a maximum chemical yield of 99%. From a screening of the structure of a catalyst, it was found that both a quaternary ammonium cation and a basicity of the counter anion were essential to catalyze the carboxylative cyclization of the propargylic amines with CO2.
