A copper-catalyzed one-pot multicomponent protocol has been developed for construction of spiro heterocycles. The domino approach leads to the synthesis of spiro oxazolidinones starting from ketones, arylacetylenes, and isocyanates via catalytic addition, hydroamination, and cyclization involving consecutive C–C, C–O, and C–N bond formations.
