摘要:
AbstractPalladium‐catalyzed asymmetric [4+3] cycloadditions of indene‐2‐carbaldehydes and 4‐vinyl benzoxazinanones proceeded smoothly in the presence of chiral phosphine ligands to give the corresponding functionalized 5H‐benzo[b]azepines (26 examples, 60% to 89% yield, 88:12 to 95.5:4.5 er) under mild conditions.magnified image
