Chen, Zicong published the artcilePd-Catalyzed Cross-Coupling of Highly Sterically Congested Enol Carbamates with Grignard Reagents via C-O Bond Activation, COA of Formula: C27H39ClN2, the publication is Organic Letters (2020), 22(10), 3879-3883, database is CAplus and MEDLINE.
The palladium-catalyzed cross-coupling reaction of enol carbamates to construct highly sterically congested alkenyl compounds was presented for the first time. This protocol demonstrated the potential of using thermally stable and highly atom-economic enol electrophiles as building blocks in bulky alkene synthesis. This reaction accommodates a broad substrate scope with excellent Z/E isomer ratios, which also provided a new synthetic pathway for accessing Tamoxifen.
