With the norbornyl system, exo addition of 3 was very likely favored with both the ketone and its acetal, but, as can be seen in entry 5, this system showed the largest, yet obviously different, stereoselectivities with ketone and acetal

3 gave a 1.2:1 mixture of 36a and its epimer 36c in a total yield of 36%. As this process showed essentially no stereoselectivity, reactions of acetals with 4 were not pursued further
