Sulfoxides can directly be converted into N-cyanosulfilimines using a new Burgess-type reagent. By applying this strategy with a related reagent variant, synthetically valuable NH-sulfoximines have been prepared from sulfoxides via N-protected sulfilimines. The practical three-step reaction sequence ...
Burgess-type reagentdehydrationnitrileoxidationoximeThree new versions of the Burgess reagent were synthesized and their thermal stability investigated by NMR. The new reagents exhibited improved reactivity toward epoxides, diols, and vinyl oxiranes as compared with the original version....
