The title compounds, spiro[1,3-dioxolane-2,3′-indolin]-2′-one, was synthesized with isatin and 2-chIoroethanol by a intramolecular substitution reaction in the presence of K2C03 for the first time, which avoided the using of H+ as catalyst in traditional synthesis of ketal compounds. The structure of spiro[1,3-dioxolane-2,3′-indolin]-2′-one was studied by X-ray single crystal diffraction, and the two byproducts in the reaction were characterized by H1-NMR, MS spectrums. With these results, the proposed way to spiro[1,3-dioxolane-2,3′-indolin]-2′- one and the two byproducts was brought forward.
