Synthesis of benzo-ortho-thiazines S-oxides by diels-alder reaction of N-sulfinylanilines with norbornadiene
From substituted N-sulfinylanilines acting as dienes in the Diels-Alder reaction with norbornadiene S-oxides of benzo-ortho-thiazines were obtained, which were oxidized into the corresponding S,S-dioxides belonging to the class of hybrid thiazinesulfonami

Synthesis of six-membered cyclic sulfonimidamides
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

Substituted N-aryl alk-1-enesulfinamides: Preparation, properties and conversion into the corresponding indole compounds [1]
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,.
6?-Cycloadditions of Aryl and New Heteroaryl N-Sulphinylamines With 2,3-Dimethylbuta-1,3-diene: Synthesis, Kinetics, Substituent Effects, Theoretical Calculations, and Reaction Mechanism
A range of new N-sulphinylamine derivatives of heteroaryl rings, including tetrazoles, oxadiazoles, thiadiazoles, thiazoles, and oxazoles is reported.The influence of the -N=S+-O- group on the n.m.r. spectra of the ring to which it i
