Palladium-catalyzed cyclization/cyclopropanation reaction for the synthesis of fused N-containing heterocycles

Palladium-catalyzed cyclization/cyclopropanation can be used to convert a range of substituted cyclic N-aryl allyl/methallyl amines efficiently and selectively to the corresponding fused tetrahydropyridine/cyclopropane-fused isoquinoline derivatives via β-hydrogen elimination or a domino sequence.
