Thermal cyclisation of 2-nitrophenyl- and 3-nitrohetaryl-ethanoate derivatives in xylene is facilitated indirectly by 5 Å molecular sieves affording an efficient general method for the construction of synthetically useful 3,4-fused isoxazoles; evidence for the mechanism of these novel heterocyclisation reactions is presented.
5 Å 分子筛间接促进了 2-硝基苯基和 3-硝基苯甲酰乙二酸酯衍生物在二甲苯中的热环化,为合成有用的 3,4-融合异噁唑提供了一种高效的通用方法;为这些新型杂环化反应的机理提供了证据。
