- Abstract
Catalyzed by 10 mol-% PhCO2H, the [3+2] cycloaddition between 3-isothiocyanato oxindoles and nitroso compounds proceeded readily to deliver 1,2,4-oxadiazolidine-3-thione-fused spirooxindoles in 40-82 % yield. The structures of the title compounds were firmly confirmed by X-ray single-crystal structure analysis.
