Abstract

Synthesis of 3-Arylbenzo[1,4]dioxin-2-carboxamides by Palladium-Catalyzed Coupling of Vinylstannanes with Aryl Halides.-In continuation of work on therapeutically valuable benzodioxinic compounds, a general and efficient procedure for the synthesis of the title compounds (12 examples) is reported. -(KHATIB, S.; MAMAI, A.; GUILLAUMET, G.; BOUZOUBAA, M.; COUDERT, G.; Tetrahedron Lett. 38 (1997) 32, 5635-5638; Inst.
