subsequent CC and CN bond‐forming intermolecular‐cascade cyclization processes is demonstrated by development of the unprecedented Lewis acid property of non‐toxic FeCl3⋅6H2O. Aromatic, aliphatic, α,β‐unsaturated, chiral sugar‐based and chromone aldehydes were regio‐ and stereoselectively cyclized with acetoacetanilides toward construction of valuable N‐containing highly functionalized 2‐pyridones (see
