RSC Advances is issuing this correction to notify readers that there are portions of text overlap with a number of different sources, and the text should have been rewritten to avoid the overlapping text. In addition, the authors regret that part of Section 5.23 was written incorrectly and should have been referenced to make it clear that this mechanism was described by Nicewicz and co-workers.
It should be shown as below:
The plausible mechanism as proposed by Nicewicz and co-workers is depicted in Scheme 39. According to this mechanism, if “ketone first” reduction is operative, a ketyl radical 72A is formed, which can undergo a radical 5-exo-trig cyclization with the corresponding olefin to provide a carbon-centered radical 72C. Then, terminal HAT can occur to give the corresponding cyclized product 73. Alternatively, when “olefin first” reduction occurs, they proposed that the olefin radical anion 72B formed, can undergo a two-electron attack at the carbonyl to generate 72C. Subsequent HAT from either DIPEA or 1,4-CHD can trap out the corresponding cycloadduct 73.^67^
