| Abstract: | Hydrazine is regioselectively condensed with a mixture of acetaldehyde and H2S at a temperature below −10 °C to form 2,4,6,8-tetramethyl-3,7-dithia-1,5-diazabicyclo3.3.0]-octane. The reaction at 0 °C with the reverse order of mixing of the starting reagents affords 2,4,6-trimethyl(1,3,5-dithiazinan-5-yl)amine as the major product. |
