  Photo SN-bond cleavage and related reactions of thianthrene sulfilimine derivatives

  摘要：

  Several 1- and 2-substituted thianthrene sulfilimine derivatives were prepared and the selectivity toward oxidation and N-tosylimination under several conditions was studied. In the photolysis of trans-5-(N-p-tosyl) iminothianthrene 10-oxide (trans-10), photo isomerization to cis-10 was observed. Further, photoimino-transferreaction of sulfilimines and their 10-mono- and -dioxide derivatives to sulfides was intensively studied to make clear the ability as nitrene precursors.

  5-(N-p-Tolulnesulfonyl)iminothianthrenes, whose sulfur atoms are oxidized to a sulfoxide or sulfone at the 10-position. were hydrolysed readily in high yield to N-unsubstituted-suifilimines by using concentrated H2SO4. During hydrolysis, 10-monoxy-5-N-unsubstituted-sulfilimines were obtained as a separable mixture of the cis and trims isomers. The stereochemical interconversion of these compounds was studied under both hydrolytic and thermal conditions and their structures were elucidated by using X-ray crystallography.

  5-(N-Bromo)iminothianthrene (2) and 5-(N-bromo)iminothianthrene 10-oxide (5) and 10,10-dioxide (8) were prepared and their alkaline hydrolyses were studied. The compound 2 and cis-5-(N-bromo)iminothianthrene 10-oxide (cis-5) afforded the corresponding sulfoximine exclusively. While, unexpectedly, both trans-5-(N-bromo)iminothianthrene 10-oxide (trans-5) and 8 afforded mainly de-brominated products, trans-5-iminothianthrene 10-oxide (trans-4) and 5-iminothianthrene 10,10-dioxide (7), respectively. In these cases, 5-iminothianthrene 5, 10-dioxide (6) (Z- and E-mixture) and 5-iminothianthrene 5, 10, 1 0-trioxide (9) and further de-iminated products were also formed respectively as minor products. The stereochemical considerations on the S-N reactions are described in view of the steric effect and 'flip-flap' motion of the thianthrene framework. (c) 2006 Elsevier Ltd. All rights reserved.
