4a, b. The other route involves the base-catalyzed multi-step one-pot reaction of aryl methyl ketones with the appropriate arylidenemalononitriles 6, 11a, b. Careful study of the synthesis of 2a, b from 1a, b revealed the importance of controlling the reaction conditions. Thus, 1,7-dioxo-4,4-heptanedicarbonitriles 3a, b or 3-pyridinecarbonitrile 4a were obtained in addition to the desired 2a, b under
描述了3-吡啶腈的简便合成方法。第一种方法涉及将碱式催化的4-羟基-1,1-环己烷二腈2a转化为4a,b。另一途径涉及芳基甲基酮与适当的亚芳基丙二腈6、11a ,b的碱催化的多步一锅法反应。从1a,b合成2a,b的仔细研究表明控制反应条件的重要性。因此,在不同的碱性条件下,除所需的2a,b外,还获得了1,7-二氧代-4,4-庚二碳腈3a,b或3-吡啶碳腈4a。
