Jordan-Hore, James A. published the artcileMild and Ligand-Free Pd(II)-Catalyzed Conjugate Additions to Hindered γ-Substituted Cyclohexenones, Formula: C10H12F6N4O6PdS2, the publication is Organic Letters (2012), 14(10), 2508-2511, database is CAplus and MEDLINE.
Ligand-free cationic Pd(II) catalyst with NaNO3 as an additive is a highly active catalytic system for conjugate additions to sterically hindered γ-substituted cyclohexenones. More challenging γγ- and βγ-substrates also react well to produce products with quaternary centers in good dr. The conjugate additions occur in a diastereoselective fashion under mild, practical and air-stable conditions, using readily available com. reagents.
