Molybdenum trioxide (MoO3) catalyzed efficient oxidative cross-dehydrogenative-coupling (CDC) method for C–H functionalization of N-aryl tetrahydroisoquinolines has been explored. This user-friendly method of synthesizing α-aminophosphonates employs 1.1 equiv of dialkyl-H-phosphonate under aerobic condition.
