Synthesis of N-Aryl-3,5-dichloro-4H-1,2,6-thiadiazin-4-imines from 3,4,4,5-Tetrachloro-4H-1,2,6-thiadiazine

Organic Letters, 2015
Condensation of 3,4,4,5-tetrachloro-4H-1,2,6-thiadiazine with a range of anilines gave 22 N-aryl-3,5-dichloro-4H-1,2,6-thiadiazin-4-imines in 43-96% yields. The scope and limitations of this condensation are briefly investigated. Furthermore, mono- and bis-substitution of the C-3 and C-5 chlorines of 3,5-dichloro-N-phenyl-4H-1,2,6-thiadiazin-4-imine by

New 1,2,6-thiadiazine dioxide acyclonucleosides: Synthesis and antiviral evaluation

Bioorganic & Medicinal Chemistry, 1995
New acyclonucleosides derived from 1,2,6-thiadiazine dioxide systems have been synthesized. Lipase-mediated deacylation procedure was used to obtain the deprotected derivatives. All the newly prepared compounds were tested as antiviral agents, but none of them showed significant activity.
