Various 7-substituted 6,7-dihydro-5H-pyrrolo[3,4-b]pyridin-5-ones are synthesized by the reaction of the corresponding 7-hydroxy derivatives with nucleophiles involving active methylene compounds, aromatics, alcohols, p-toluenethiol, benzenesulfinic acid, triethyl phosphite, ammonia, and amines under acidic or basic conditions. Some synthetic applications of the products obtained are demonstrated to give a 7-methylene derivative and fused tricyclic derivatives.
通过相应的7-羟基衍生物与活性亚甲基化合物、芳香族化合物、醇、对甲苯硫醇、苯磺酸、三乙基磷酸酯、氨和胺在酸性或碱性条件下反应,合成了多种7-取代的6,7-二氢-5H-吡咯[3,4-b]吡啶-5-酮。一些合成产物的应用示例显示了生成7-亚甲基衍生物和融合的三环衍生物。
