Tsimelzon, Anna,Braslau, Rebecca
, p. 10854 - 10859 (2007/10/03)
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 m
