1992
Methyl hexahydro-3-methyl-6-thioxo-1,2,4,5-tetrazine-3-nonanoate (I) on treatment with reagents such as chloroacetic acid, 1,2-dibromoethane and 2-mercaptoethanol under different reaction conditions afforded methyl 3,4,6,7-tetrahydro-3-methyl-6-oxo-2H-thiazolo[3,2-b]-1,2,4,5-tetrazine-3-nonanoate (II), methyl 3,4,6,7-tetrahydro-3-methyl-2H-thiazolo[3,2-b]-1,2,4,5-tetrazine-3-nonanoate (III) and methyl 8-methyl-1-oxa-4-thia-6,7,9,10-tetraazaspiro-[4.5]-decane-8-nonanoate (IV) in good yields. The structures of compounds II–IV were established by elemental analysis, infrared (IR), nuclear magnetic resonance (NMR), and mass spectral data.
