A palladium-catalyzed C–H
functionalization/intramolecular
asymmetric allylation cascade of N-sulfonyl benzamides
with 1,3-dienes has been developed. In the presence of a chiral pyridine–oxazoline
ligand, this protocol enables the synthesis of chiral 3,4-dihydroisoquinolones
in yields of up to 83% with enantioselectivities of up to 96%, using
environmentally friendly air as the terminal oxidant.
