Control experiments for the acetals 3 and 9, for which the two anomers of starting material are separable, indicate that both anomers give the same product with the same degree of selectivity. Stereoselectivities depend on Lewis acid to only a minor extent.

Preliminary computational studies suggest that although both oxocarbenium ions 17 and 19 are of comparable energy, the product 20 derived from 19 should be strongly destabilized by this 1,3-diaxial interaction.
