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.

Cylopentanone oxime reacts with S2Cl2at 4 °C in tetrahydrofuran containing a base, or in dimethylformamide, to give deep-violet crystals of the 10π-heteroaromatic trichlorocyclopenta-1,2,3-dithiazole 7 without isolable intermediates; other 1.2,3-dithiazoles (2, 4, 10, 12, 13, and 15) are readily formed similarly.
