Sen, Indira,Kloer, Daniel,Hall, Roger,Pal, Sitaram
, p. 3018 - 3028 (2013/11/06)
A general synthetic route to six-membered cyclic N-aryl- and N-alkyl-substituted sulfonimidamides via an intramolecular ring closure of suitably functionalised acyclic sulfonimidamides is described. The structure of this new ring system was confirmed by v
