A variety of N-vinyl and N-aryl amides were converted in one step into the corresponding pyrimidine and quinazoline derivatives, respectively. Amide activation with trifluoromethanesulfonic anhydride in the presence of 2-chloropyridine followed by nitrile addition to the activated amide derivative and annulation provides the desired azaheterocycles.
各种 N-乙烯基和 N-芳基酰胺在一个步骤中分别转化为相应的嘧啶和喹唑啉衍生物。在 2-氯吡啶存在下,先用三氟甲磺酸酐进行酰胺活化,然后将腈加到活化的酰胺衍生物中并环化,就得到了所需的杂杂环。
