The first complete study of relative stereocontrol in an intramolecular 4+3 cycloaddition has been performed. Thus, CH2Cl2 solutions of alkoxyallylic sulfones 5, 7, and 9 were treated with TiCl4 at −78°C to give diastereomeric cycloadducts in fair

Initial allyl cation geometry appears to be irrelevant with respect to the stereochemistry of cycloadducts in the intramolecular 4+3 cycloaddition of alkoxyallylic cations derived from alkoxyallylic sulfones.
