In the reaction of a-stannyl radical addition to carbonyl to form six-membered ring, we constructed a sulfonyl group at the a position of the formyl group to inhibit 1,5-H shift in order to increase the cyclization product yield. We obtained 41 % yield of the cyclization product in this system.

在 a-锡基自由基加成到醛基形成六员环的系统中，我们在醛基的 a 位上加入碸基来抑制 1，5-氢转移并提升环合产物之产率，在这个系统中，我们得到了 41 %的环合产物。
