In this Letter we explored the regioselective cyclization of 2-bromophenylalanine derivatives to access enantiopure dihydroquinolinones via an intramolecular regioselective Buchwald–Hartwig cyclization using Pd2(dba)3/XPhos as a catalytic system in the presence of BTPP as organic base. This procedure represents a promising strategy for the direct synthesis of bridged Phe-Xaa dipeptides.
