A new highly efficient method for the catalyst‐free synthesis of germinal spiro compounds through a one‐pot three‐component condensation reaction of carbon dioxide, amines and dimethyl acetylenedicarboxylate at room temperature is described. In this methodology, both C=O bonds of CO 2 are concurrently reacting in a one‐pot reaction. The structures of all obtained products were assigned with 1 H and 13 C NMR, MS, IR and elemental analysis.
