synthesized by a new methodology using microwave irradiation, in short time (20–30 min), in low power (50–70 W), and in 34–92% yield. Among all methodologies evaluated, no side products were obtained. All derivatives were completely characterized by FT–IR, 1H and 13C NMR, GC–MS, and HRMS.
通过微波辐射,短时间(20–30分钟),低功率(50–70 W)和34–92微波辐射的新方法,合成了28种吡唑-咪唑啉1a – n和2a – n杂种% 屈服。在所有评估的方法中,没有获得副产品。所有衍生物均通过FT-IR,1 H和13 C NMR,GC-MS和HRMS进行了完全鉴定。
