salicylic aldehydes and acetylacetic ester leading to the formation of novel 2,3-dihydrochromeno[4,3-d]pyrazolo[3,4-b]pyridine-1,6-diones was discovered. The elucidation of the reaction scope revealed that 5-aminopyrazoles, 3-amino-1,2,4-triazoles and 6-aminouracil could be used as the heterocyclic amine component. Selected heterocyclic products were found to possess notable antibacterial activities.
3-氨基吡唑-5-酮与取代水杨醛和乙酰乙酸酯的多组分反应导致形成新型2,3-二氢色基[4,3- d ]吡唑并[3,4- b ]吡啶-1,6-迪奥内斯被发现。反应范围的阐明表明5-氨基吡唑、3-氨基-1,2,4-三唑和6-氨基尿嘧啶可用作杂环胺组分。发现选定的杂环产品具有显着的抗菌活性。
