Solvent-free incorporation of CO(2) into 2-oxazolidinones: a review

This review is an attempt to give an overview on the recent advances and developments in the synthesis of 2-oxazolidinone frameworks through carbon dioxide (CO(2)) fixation reactions under solvent-free conditions. The cycloaddition of CO(2) to aziridine derivatives is discussed first. This is followed by carboxylative cyclization of N-propargylamines with CO(2) and three-component coupling of epoxides, amines, and CO(2). Finally, cycloaddition of CO(2) to propargylic alcohols and amines will be covered at the end of the review. The literature has been surveyed up until the end of 2018.
