Abstract

Biologically active 3H-pyrrolo[2,3-c]quinolin-4(5H)-ones have been synthesized in an efficient and concise manner utilizing readily available 4-hydroxyquinolin-2(1H)-ones as the starting material. The key strategy relies on the construction of the pyrrole ring through the palladium catalyzed sequential cross-coupling reaction and cyclization process.
