Imidazo[1,2-a]benzoazepines were prepared by Brønsted acid-mediated intramolecular alkyne-carbonyl metathesis (ACM). The starting materials, imidazole and benzimidazole derivatives, were prepared by N-alkylation, formylation and Sonogashira cross-coupling reaction. The final intramolecular ACM delivered the final products in good to excellent yields and with a wide tolerance towards functional groups
咪唑并 [1,2- a ] 苯并氮卓类化合物是通过 Brønsted 酸介导的分子内炔烃-羰基复分解反应 (ACM) 制备的。原料咪唑和苯并咪唑衍生物通过N-烷基化、甲酰化和Sonogashira交叉偶联反应制备。最终的分子内 ACM 以良好到极好的收率交付最终产品,并且对官能团具有广泛的耐受性。
