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.
摇摆的结果:使用N杂环卡宾催化剂时,1,2-噻嗪丁-3-氧化物的两种对映体均以非常高的收率获得,并具有出色的对映选择性(参见方案; MS =分子筛,TBS =叔丁基二甲基甲硅烷基)。产物可以通过氧化或还原轻松地转化为3-氧代-β-杜马酰胺,α-巯基酰胺和β-巯基胺。

obtained liquid compound were studied by Raman and infrared spectroscopy in the liquid state. The assignment of the vibrational spectra was carried out with the help of data obtained by quantumchemicalcalculations at the harmonic oscillator approximation and using anharmonic vibrational self-consistent field (VSCF) method as well. The 1H and 13C NMR chemical shifts of the molecule were calculated by
Aromatic and aliphatic N-sulphinyl amines add smoothly to diphenyl and biphenylene ketene forming substituted 1,2-thiazetidinone-(3)-oxides-(1). An addition of ketene itself to N-sulphinyl cyclohexyl amine can be concluded from secondary products only.

Treatment of amine derivatives such as amines, sulfonamides, and amides with N,N′-sulfinylbisimidazole and N-(chlorosulfinyl)imidazole respectively gives the corresponding N-sulfinylamine derivatives (); the latter reaction using N-(chlorosulfinyl)imidazole yields in almost quantitative yields at 20°C under mild conditions.
