The first synthesis of N-tosyl imines from various cyclopent-2-enones and cyclohex-2-enones was achieved by direct condensation with tosyl amide in the presence of TiCl(OEt)(3) and Et3N. In addition, N-tert-butylsulfonyl imines from five- to seven-membered cycloalk-2-enones were obtained through formation of the respective oximes and subsequent Hudson reaction. These compounds are easy to handle solids and they are interesting starting materials for a variety of transformations.
