Synthesis of Novel 6H‐Furo[3,2‐e]Indole Derivatives via One‐Pot Three Component Reactions

Abstract

ABSTRACTA one‐pot, three‐component reaction of ethyl 5‐aminobenzofuran‐2‐carboxylate, arylglyoxals and cyclic 1,3‐dicarbonyl compounds in the presence of acetic acid as an organocatalyst in ethanol medium under reflux conditions provided a series of new 6H‐furo[3,2‐e]indole derivatives in good yields.
