AbstractA tunable aromatic CH insertion and a Wolff rearrangement of α‐diazo β‐keto esters precursor were developed. Different directing groups on nitrogen led with high selectivity to either dihydroquinoline or 2‐carbamoylacrylate motifs, which can be transformed to multiple heterocyclic scaffolds.magnified image
