An efficient one-pot synthesis of oxazolidinones was developed through CuI/DBU/MS joint system-catalyzed carboxylative cyclization of arylacetylene, arylaldehyde, and arylamine in water medium under a 1 atm carbon dioxide (CO2) atm. The 4 Å mol. 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.
Journal of Organic Chemistry published new progress about Alkynes, α- Role: RCT (Reactant), RACT (Reactant or Reagent) (aryl). 3959-07-7 belongs to class bromides-buliding-blocks, and the molecular formula is C7H8BrN, Category: bromides-buliding-blocks.
