Highly Stereoselective Brønsted Acid-Catalyzed Synthesis of Spirooxindole Pyrans
[Image: see text] A Brønsted acid-catalyzed Prins-type cyclization sequence to construct spirooxindole pyrans in high yields and excellent diastereoselectivity has been developed. The combination of a β-hydroxy dioxinone fragment and isatin dimethyl acetal generate oxa-spirooxindoles efficiently. Th...
