ortho-Nitrobenzaldehyde and trimethylsilyl azide were used in a Ugi-Cadogan cascade towards tetrazolyl indazoles. After the Ugi step, the intermediate tetrazoles were not purified but directly heated with triethyl phosphite to form the final indazoles.
使用邻硝基苯甲醛和三甲基硅叠氮化物进行乌基-卡多根级联反应,生成四唑基吲唑。在 Ugi 步骤之后,中间的四唑没有被提纯,而是直接与亚磷酸三乙酯一起加热,形成最终的吲唑。
