Abstract
AbstractSynthesis of 2,3,6‐triisubstituted β‐carbolin‐1‐ones is disclosed using palladium‐catalyzed intramolecular amination of 3‐amino‐4‐(2‐bromophenyl)‐2‐pyridones prepared by the conjugate addition reaction of diethyl 2‐aminomalonate having a bulkier ketimine moiety to alkynyl imines. The transformation of the synthesized 3‐amino‐4‐(2‐bromophenyl)‐2‐pyridones using palladium‐catalyzed intramolecular amination produced 2,3,6‐trisubstituted β‐carbolin‐1‐ones in good to high yields.
