The pyrrolo[2,3‐b]pyridine core structure, a bioisostere of quinolones, is found in several molecules that possess important biological activity. We describe here a new, concise, three‐step synthesis of pyrrolo[2,3‐b]pyridines starting from L‐alanine. A series of 4,7‐dihydro‐4‐oxo‐1H‐pyrrolo[2,3‐b]pyridine‐5‐carboxylic acid derivatives, which have not been previously reported, were synthesized using
在几个具有重要生物活性的分子中发现了吡咯并[2,3- b ]吡啶核心结构,是喹诺酮类的生物等排体。我们在这里描述了一种新的,简洁的,三步合成的从L-丙氨酸开始的吡咯并[2,3- b ]吡啶。使用此方法合成了以前未报道的一系列4,7-二氢-4-氧代-1 H-吡咯并[2,3 - b ]吡啶-5-羧酸衍生物。
