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.
