Reaction of 4-fluoro-N-sulfinylaniline with norbornene and norbornadiene has afforded the Diels-Alder adducts of benzothiazine structure that have been oxidized into the corresponding benzothiazine sulfonamides. Structure of the obtained compounds and ste

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

Reaction of vinylic organometallic derivatives with N-sulfinyl arenamines 2 affords the title sulfinamides 3. On heating their solutions in selected solvents to 80-124 °C, these sulfinamides are converted into the corresponding indoles 6, probably via a [3.3]-sigmatropic rearrangement to intermediates VIII which undergo an intramolecular carbophilic reaction of the nitrogen atom with the neighboring sulfine group, followed by elimination of HSOH. The triethyloxonium tetrafluoroborate- or boron trifluoride etherate catalyzed conversion 3 → 6 can be carried out at a much lower temperature. Elsevier,.
