Palladium‐Catalyzed Enantioselective Migratory Hydroamidocarbonylation of Amide‐Linked Alkenes to Access Chiral α‐Alkyl Succinimides

Abstract

A Pd‐catalyzed asymmetric isomerization‐hydroamidocarbonylation of amide‐containing alkenes was developed, affording a variety of chiral a‐alkyl succinimides in moderate to good yields with high enantioselectivities. The key to success was introducing bulky 1‐adamentyl P‐substitution and 2,3,5,6‐tetramethoxyphenyl group into the rigid P‐chirogenic bisphosphine ligand to create stronger steric hinderance and deeper catalytic pocket. By this approach, regio‐ or stereo‐convergent synthesis of enantiomeric succinimides from the mixture of olefin isomers was achieved.
