- 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

- N-heterocyclic carbene catalysis: Enantioselective formal [2+2] cycloaddition of ketenes and N-sulfinylanilines
-
Sultam of swing: Both enantiomers of 1,2-thiazetidin-3-one oxides were obtained in very good yields with excellent enantioselectivities when using N-heterocyclic carbene catalysts (see scheme; M.S.=molecular sieves, TBS=tert-butyldimethylsilyl). The products were easily converted into 3-oxo-β-sultams, α-mercapto amides, and β-mercapto amines through oxidation or reduction. Copyright

- A-new synthesis of N-sulfinylamines via β-elimination of chloroform from trichloromethanesulfinamides
-
The synthesis of various N-monosubstituted trichloromethanesulfinamides by two alternative and novel procedures is described. All these compounds have been found to undergo base-induced elimination of chloroform with formation of the corresponding N-sulfinylamines. Reaction proceeds smoothly under mild conditions.

- 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,.

- 1,2-Thiazines and Related Heterocycles. Part 1. An Investigation of the Cycloadditions of N-Sulphinylanilines with 1,4-Epoxy-1,4-dihydronaphthalene and Other Alkenes
-
Evidence is adduced from the character of the alkenes which cycloadd to N-sulphinylanilines and from a kinetic investigation of the reactions of N-sulphinylanilines with 1,4-epoxy-1,4-dihydronaphthalene, examining the effects upon reaction rate of solvent polarity, temperature, and substitution in the N-sulphinylanilines, that the cycloadditions are pericyclic reactions of Diels-Alder type with inverse electron demand.A degree of charge separation in the transition state is indicated but this is small and confined essentially to the sulphinylaniline moiety.

N-Sulphinylanilines react with malonyl dichloride to give 6-chloro-4-hydroxy-2-oxopyran-3-carboxanilides with loss of the sulphoxide moiety as thionyl chloride.Milder conditions and electron-withdrawing substituents do not alter the course of the reaction of thiocyanates with malonyl dichloride to give 2-substituted-thio-7-chloro-4H,5H-pyranooxazine-4,5-diones.
