DOI: 10.1021/acs.orglett.2c03413
Abstract: Herein, we report Ni-catalyzed intramolecular carboacylation of imides containing a tethered alkene and tetraarylborate nucleophiles. Using a nickel-phosphine catalyst system, α-substituted, γ-amino ketones are generated in up to 92% yield with site selectivity. Deprotection and… read more here.
