Finally, due to the importance of the lactams, 11 the scope of this MC-CCR was examined (Scheme 4). Overall, a wide range of different sizes of N-vinyl lactams were compatible in this one-pot procedure including g-lactams (6a-e), b-lactams (6g) and e-lactams (6h). Notably, compound 6f was formed with a modest diastereomeric ratio (3:2) using the corresponding chiral N-alkenylpyrrolidinone. Remarkably, the N-vinyloxazolidinone and N-methyl-N-vinylacetamide were also applicable to the reaction (6i and 6j), thus demonstrating complementary reactivity of this iron catalyzed MC-CCR in comparison to nickel-based systems.
