Solvent-Dependent Divergent Functions of Sc(OTf)(3) in Stereoselective Epoxide-Opening Spiroketalizations

[Image: see text] A stereocontrolled synthesis of benzannulated spiroketals has been developed using solvent-dependent Sc(OTf)(3)-mediated spirocyclizations of exo-glycal epoxides having alcohol side chains. In THF, the reaction proceeds via Lewis acid catalysis under kinetic control with inversion...
