The 4 ? molecular sieves (MSs) were added to improve CO2 capture and facilitate carboxylation to give the products in high yields. The CuI/DBU/MS system is robust and highly effective for the reactions with different substrates, and some target products were obtained in an excellent yield of ?96%, with no side products in the final step. ?Carbon dioxide; Carboxylation; Molecular sieves; Sieves; Aryl acetylenes; Arylaldehyde; Different substrates; Joint system; One-pot synthesis; Oxazolidinones; Side products; Water mediums; Cyclization[SDGs]SDG6[SDGs]SDG13journal article10.1021/acs.joc.0c018332-s2.0-85094665186
