Novel 1, 3, 4-thia(oxa)diazoles containing thienyl groups were synthesized. Analogous to the naturally-occurring compound, a-terthienyl, they can be photosensitized by ultraviolet light and showed phototoxicities against the 2nd instar larvae of southern armyworm (Pseudaletia separata Walker), they also showed photocleavage action to pBR322 DNA. Novel 1, 3, 4-thia (oxa) diazoles containing thienyl groups were synthesized. Analogous to the naturally-occurring compound, a-terthienyl, they can be photosensitized by ultraviolet light and given phototoxicities against the 2nd instar larvae of southern armyworm (Pseudaletia separata Walker), they also exhibited photocleavage action to pBR322 DNA.
