A synthetic novel strategy involving a pseudo-three-component reaction to obtain 1,6-dihydroazaazulenes derivates via cyclization of pyrrolyl-enones was developed. This reaction is carried out under mild conditions from simple starting materials and catalyzed with ionic liquid. Notably, three new C–C bonds are formed in the one-pot process. The target molecules are of interest in medicinal chemistry as they contain a privileged scaffold and are considered indole homologues.

一种通过吡咯基烯酮环化合成 1,6-二氢氮杂芘烯的新型伪三​​组分合成策略

开发了一种合成新策略，该策略涉及伪三组分反应，通过吡咯基烯酮的环化获得 1,6-二氢氮杂氮杂环烯衍生物。该反应由简单的起始原料在温和条件下进行，并在离子液体的催化下进行。值得注意的是，在一锅法中形成了三个新的 C-C 键。目标分子在药物化学中很受关注，因为它们包含一个特殊的支架并被认为是吲哚同系物。
