Abstract
The kinetic resolution of 2-substituted-2,3-dihydro-4-pyridones was realized via a Pd-catalyzed allylic substitution reaction using a commercially available (S)-P-Phos as a ligand, affording optically active dihydropyridones and C-allylated dihydropyridones in high yields and good enantioselectivities with the S-factor up to 43. With this protocol, a catalytic asymmetric total synthesis of indolizidine (-)-209I was realized for the first time.
