摘要：

Nitrile imines undergo cycloadditions to the thiocarbonyl group of N-thioacyllactamimines 1 giving 1,3,4-thiadiazolines 2. Depending on the substituents oxidation of N-thioacyllactamimines 1 leads to different products, such as condensed 5-amino-1,2,4-thiadiazolium bromides 5, 3,5-diaryl-1,2,4-dithiazolium salts 6, 3,5-diaryl-1,2,4-thiadiazoles 7 or 2-benzothiazolyliminopyrrolidine 8.
