In the present paper, the coupling reaction of aldehyde, terminal alkyne, amine salt and CO2 was investigated. Copper iodide was found to be an efficient catalyst for the coupling reaction in ethyl acetate at 80 °C and under an atmospheric pressure of CO2. A diverse range of oxazolidinones was prepared by this method. Subsequently, a...
