The influence of substituents and temperature on the thermal cyclisation of 3-acetoxy-2-methylene-3-(2-pyridyl)propanoic esters and analogues has been explored using 1H NMR spectroscopy, and mechanistic proposals for the formation of the resulting indolizines are presented.
使用1 H NMR光谱研究了取代基和温度对3-乙酰氧基-2-亚甲基-3-(2-吡啶基)丙酸酯和类似物的热环化的影响,有关形成生成的吲哚嗪的机理建议是提出了。
