Titanium(IV)-Catalyzed Stereoselective Synthesis of Spirooxindole-1-pyrrolines
[Image: see text] A stereoselective cyclization between alkylidene oxindoles and 5-methoxyoxazoles has been developed using catalytic titanium(IV) chloride (as low as 5 mol %) to afford spiro[3,3′-oxindole-1-pyrrolines] in excellent yield (up to 99%) and diastereoselectivity (up to 99:1). Using a ch...
