An efficient condensation reaction between nitrosoimidazoles and phenyl methylcarbazate forms the basis of a new synthetic route to phenyloxycarbonyl substituted triazenylimidazoles. Exposure of these triazenes to diffuse daylight is sufficient to induce (E) to (Z)-isomerization of the triazene –NN– bond, resulting in spontaneous formation of temozolomide in high yield.
亚硝基咪唑和甲基咔嗪酸苯酯之间的高效缩合反应为苯氧羰基取代的三嗪基咪唑的新合成路线奠定了基础。将这些三氮烯暴露在扩散的日光下,足以诱导三氮烯 -NN- 键的(E)到(Z)异构化,从而自发形成高产率的替莫唑胺。
