Synthesis of 2,3-diaryl-5H-imidazo[2,1-a]isoindol-5-ones via the one-pot reaction of 1,2-diketones, 2-formylbenzoic acids, and ammonium acetate
摘要:
We describe a new one-pot synthesis of 2,3-diaryl-5H-imidazo[2,1-a]isoindol-5-ones via the reaction of 1,2-diketones, 2-formylbenzoic acids, and ammonium acetate in acetic acid under reflux conditions and in the absence of a catalyst. (C) 2012 Elsevier Ltd. All rights reserved.
Several imidazo[2,1‐a]isoindoles, an interesting class of polycyclic heteroarenes, were prepared, for the first time, by a Pd(II)/Ag(I)‐promoted intramolecular cross‐dehydrogenativecoupling involving the corresponding 1‐benzylimidazoles.
通过Pd(II)/ Ag(I)促进的分子内跨脱氢偶联,涉及相应的1-苄基咪唑,首次制备了几种有趣的多环杂芳烃类咪唑并[2,1– a ]异吲哚。 。
