A series of chromeno[4,3‐d]isoxazolo[5,4‐b]pyridin‐6‐one derivatives were easily and efficiently synthesized by the reaction of 3‐acyl‐2H‐chromen‐2‐ones with isoxazol‐5‐amine in acetic acid. Some synthesized compounds were evaluated for their antiproliferative properties in vitro against cancer cells, and these compounds were found to have some activities.
通过3酰基2 H铬2-2-酮与异恶唑5的反应可以轻松,高效地合成一系列chromeno [4,3- d ]异恶唑并[5,4 ‐ b ]吡啶-6-酮衍生物‐乙酸中的胺。评价了一些合成的化合物在体外对癌细胞的抗增殖性能,发现这些化合物具有一定的活性。

A series of chromeno[4,3‐d]pyrazolo[3,4‐b]pyridin‐6(3H)‐one derivatives was easily and efficiently synthesized by the reaction of 2H‐chromen‐2‐ones with pyrazol‐5‐amines catalyzed by CuCl2⋅2H2O in ethanol. This protocol has the advantages of mild reaction conditions, easy work‐up, and high yields. These compounds were showed to have high fluorescence quantum yields, which mentioned their value as luminescence
