Abstract Regioselective synthesis of 6a,7,8,12b‐tetrahydro‐6H‐chromeno[3,4‐c]quinolin‐6‐ones 4 in good to excellent yields from 3‐(2‐bromoanilinomethyl)coumarins 3 by aryl radical cyclization is described. The cyclization precursors 3 were prepared by the reaction of 3‐chloromethyl coumarin with different 2‐bromoaniline.
