One‐Pot Three‐Component Synthesis of 6H‐chromeno[4,3‐b] or Cyclopenta[b]furo[3,2‐f]quinoline Derivatives |
| |
Abstract: | Two series of furo[3,2‐f ]quinoline‐2‐carboxylate were obtained via a three‐component reaction of aldehydes, 5‐aminobenzofuran‐2‐carboxylate, and 4‐hydroxy‐2H‐chromen‐2‐one or cyclopentane‐1,3‐dione in DMF under catalyst‐free condition in high yields. This one‐pot three‐component reaction provided an efficient method for the synthesis of fused polycyclic heterocycles for bioactive screening. |
