The synthesis of potentially bioactive pyrroloazepinones based on the catalytic intramolecular cyclization of alkyne-substituted 1H-pyrrole-2-carboxylic acid amides has been developed. In the presence of either H2PtCl6·6H2O at 120 °C or AuCl3 at room temperature pyrrolo[3,2-c]azepin-4-ones are formed.
已经开发了基于炔烃取代的1 H-吡咯-2-羧酸酰胺的催化分子内环化反应的潜在生物活性吡咯并ze庚酮的合成方法。在120°C下存在H 2 PtCl 6 ·6H 2 O或在室温下存在AuCl 3的情况下,会生成吡咯并[3,2 - c ] azepin-4-ones。
