Synthesis of 5 H -Pyrrolo[3,4- b ]Pyridin-5-Ones via a Cerium Chloride Catalyzed Multicomponent Cascade Process: A One-Pot Approach Incorporating Ugi-Zhu 3CR, Aza Diels–Alder, N -Acylation, and Aromatization Reactions

Polycyclic Aromatic Compounds
We have synthesized α-isocyano-β-phenylpropionamides 5 (a–c) using a two-step process and then created a new series of poly-substituted 5H-pyrrolo[3,4-b]pyridin-5-ones 12 (a–o) via a multi-component reaction. Most of the reported literature used scandium triflate and either benzene or toluene as solvents, which are not good for the environment. We have
