I wonder if I predicted the products correctly, because it seems to be messier than I thought - there's a pair of diastereomers... Also, I feel that the endo/exo rule does not apply here. Am I correct in my understanding? I have never seen a reaction like the one I drawn mentioned anywhere before. Hopefully someone can help me out.Thanks!
Note, there's an example in Clayden reacting cis, trans diene with DEAD, but since there's no stereocenter at nitrogen we end up just getting trans product.
