title: A novel synthesis of oxazolidine-2,4-diones via an efficient fixation of CO2 with 3-aryl-2-alkynamides.
abstract: A very mild protocol for fixation of carbon dioxide with 2-alkynamides in DMSO at 30 °C using a CO(2) balloon in the presence of K(2)CO(3) has been developed, which leads to an efficient assembly of oxazolidine-2,4-diones. It is observed that the regioselectivity was controlled by the aryl group.
