A series of 2,3-disubstituted-5-oxochromeno[2,3-b]pyridine derivatives were synthesized under ultrasound irradiation, and also under conventional methods, from the reaction of 3cyanochromones with some active methylene compounds in the presence of a stoichiometric base. The structures of the products were unambiguously elucidated by 1D and 2D NMR experiments. Full assignment of all H and C NMR chemical
一系列 2,3-二取代-5-氧代色基 [2,3-b] 吡啶衍生物在超声辐照下合成,也在常规方法下,由 3-氰基色酮与一些活性亚甲基化合物在化学计量碱存在下的反应合成. 通过一维和二维核磁共振实验明确阐明了产物的结构。已实现所有 H 和 C NMR 化学位移的完全分配。此外,还评估了合成的色诺吡啶衍生物的脂质过氧化抑制作用。
