One-pot synthesis ofN-substituted benzannulated triazolesviastable arene diazonium salts

A mild and effective one-pot synthesis of 1,2,3-benzotriazin-4(3H)-ones and benzothiatriazine-1,1(2H)-dioxide analogues has been developed. The method involves the diazotisation and subsequent cyclisation of 2-aminobenzamides and 2-aminobenzenesulfonamidesviastable diazonium salts, prepared using a polymer-supported nitrite reagent andp-tosic acid. The transformation was compatible with a wide range of aryl functional groups and amide/sulfonamide-substituents and was used for the synthesis of pharmaceutically important targets. The synthetic utility of the one-pot diazotisaton-cyclisation process was further demonstrated with the preparation of an α-amino acid containing 1,2,3-benzotriazin-4(3H)-one.

Synthesis and nematicidal activities of 1,2,3-benzotriazin-4-one derivatives containing benzo[d][1,2,3]thiadiazole against Meloidogyne incognita

Based on the characteristic of benzo[d][1,2,3]thiadiazole to induce the systemic acquired resistance and improve the immunity of plants, benzo[d][1,2,3]thiadiazole was introduced into 1,2,3-benzotriazin-4-one, thirty-one novel 1,2,3-benzotriazin-4-one derivatives containing benzo[d][1,2,3]thiadiazole were designed and synthesized. Nematicidal activity showed that most of the synthesized compounds exhibited great inhibitory activity in vivo against Meloidogyne incognita at 20 mg/L. Among 31 tested compounds, A2 and A3 showed an excellent nematicidal activity with the inhibition rate of 50.4percent and 53.1percent at the concentration of 1.0 mg/L, respectively. The influence of substituent type and position was investigated. The relationship between structure and activity was also preliminary analyzed.

Oxidative Rearrangement of 3-Aminoindazoles for the Construction of 1,2,3-Benzotriazine-4(3 H)-ones at Ambient Temperature

A novel oxidative rearrangement of 3-aminoindazoles is reported, enabling the production of diverse functionalized 1,2,3-benzotriazine-4(3H)-ones in good yields at room temperature. The key success of this unprecedented transformation of 3-aminoindazoles is the use of water as cosolvent, which could facilitate the halogen-induced ring expansion of 3-aminoindazoles under oxidative conditions.
