Herein, we disclose an interesting iron-catalyzed approach for the carbonylation of a tertiary carbon radical. The tertiary carbon radical generated from a 1,5-hydrogen atom transfer can be captured by CO gas smoothly. Various six-membered lactams were constructed chemo-selectively in high yields.

radical‐mediated synthesis of dihydronaphthalenones from oxime esters has been developed. By using iron salt as a green and inexpensive catalyst, various α‐aryl oxime esters were transformed into the corresponding dihydronaphthalenones in moderate to good yields with high chemo‐selectivities. The reaction proceeds via 1,5‐hydrogen atom transfer and then intramolecular radical cyclization sequence.
