The efficient one-pot synthesis of several new tricyclic systems of type 1 and 2, obtained from the reaction of substituted 2-amino-3-cyanopyrroles and 3-amino-4-cyanopyrroles with BMMAs, is reported. The duration and yields of the reaction strongly depend on the reactivity of the starting pyrrole and on the size of the ring to be formed. Mechanist features of the reaction were investigated and proposed
据报道,从取代的2-氨基-3-氰基吡咯和3-氨基-4-氰基吡咯与BMMAs反应中获得了几种新型的1、2型三环系统的高效一锅合成。反应的持续时间和产率在很大程度上取决于起始吡咯的反应性和要形成的环的大小。通过研究3-氨基吡咯-2,4-二氰基取代的反应性,研究并提出了反应机理。报道的方法代表了将BMMA试剂与吡咯衍生物结合使用的第一个例子,并且可以轻松,通用地进入大量迄今未知的吡咯并嘧啶类化合物,并进一步与不同大小的氮杂环进行了退火。这些新的缩聚杂环具有与DNA相互作用的必要条件。
