A biologically inspired organocatalytic one‐pot synthesis of highly functionalized pyridazines, which are ubiquitous structural units in a number of biologically active compounds, has been developed by starting from readily available diazo compounds and Morita–Baylis–Hillman (MBH) carbonates. Under mild reaction conditions, this synthetic route tolerated significant substrate variation to deliver a
从容易获得的重氮化合物和Morita-Baylis-Hillman(MBH)碳酸盐开始,已经开发出了一种由生物启发的有机催化一锅合成的高官能化哒嗪,它是许多生物活性化合物中普遍存在的结构单元。在温和的反应条件下,该合成途径可承受显着的底物变化,从而提供广泛的取代产物,包括CF 3取代的哒嗪衍生物。此外,可以通过2,2,2-三氟重氮乙烷方便地完成将三氟甲基引入哒嗪环的操作。
