Abstract

Palladium-Catalyzed C3-Selective Mono-Arylation of 4-Hydroxycoumarin. -A novel catalytic system is developed for the C3 regioselective mono-arylation of 4-hydroxycoumarin. The arylated product (IIIa) is further functionalized using Suzuki coupling. -(YAKUSHIJI*, F.; HARAMO, M.; MIYADERA, Y.; UCHIYAMA, C.; TAKAYAMA, K.; HAYASHI, Y.; Tetrahedron Lett. 55 (2014) 22, 3316-3318, http://dx.
