Radical [n + 1] annulations with sulfur dioxide.
[reaction: see text] A new methodology for [n + 1] radical annulation using sulfur dioxide as a geminal radical acceptor/donor is presented. This methodology provides a novel route to the formation of five-, six-, and seven-membered cyclic sulfones utilizing a radical chain mechanism under very mild conditions.
