Heterocyclization of hydrazine with aldehydes (R-CHO, where R = Me, Et, nPr, nBu, nPent, Ph, Ph-OCH3, 3-Py) and H2S synthesized and isolated stereoisomeric 2,4,6,8-tetrasubstituted-3, 7 ditia-1 ,5-diazabicyclo [3.3.0]-octanes. According to the XRD and 1H NMR and 13C inserted trans-transoid-trans conformation of 3,7-tetraalkilsubstituted ditia-1 ,5-diazabicyclo [3.3.0] octane.
