    • When we used N-allyl-N-benzoyl derivative as a substrate instead of N-tosyl-N-benzoyl derivative 1a, we could not obtain the products, presumably because the N-allylphenyl group is not a good leaving group as compared to the N-tosylphenyl moiety in the case of 1a. The reaction showed sluggish reactivity and much of the starting materials were decomposed to many intractable polar compounds
