Indirect conversion of ambient pressure CO2 into oxazolidin-2-ones by a copper-based magnetic nanocatalyst

Abstract

An efficient, practical and magnetically recyclable Cu-based catalytic system for the synthesis of oxazolidin-2-ones via the multicomponent reaction of carbamate salts, aromatic aldehydes and aromatic terminal alkynes was developed. The magnetic nanocatalyst, namely FeDOPACu, could efficiently promote the construction of oxazolidin-2-ones with different functional groups in good to excellent yields. Importantly, the catalyst can be easily recovered by applying an external magnet, which rendered this protocol economic and environmentally begin. This method represents an attractive heterogeneous protocol for indirect transformation of CO2 into value-added heterocyles as the carbamate salts are easily obtained by capturing CO2 with primary amines.
