RT info:eu-repo/semantics/article T1 Combined directed ortho-zincation and palladiumcatalyzed strategies: Synthesis of 4,n-dimethoxysubstituted benzo[b]furans A1 Guilarte Moreno, Verónica A1 Castroviejo Fernández, Mª Pilar A1 Álvarez Manuel, Estela A1 Sanz Díez, Roberto K1 benzo[b]furans K1 o-zincation K1 palladium K1 selectivity K1 Química orgánica K1 Chemistry, Organic AB A new route to regioselectively dialkoxy-functionalized benzo[b]furan derivatives has been developed from 3-halo-2-iodoanisolesbearing an additional methoxy group, which have been accessed through an ortho-zincation/iodination reaction. Two palladiumcatalyzedprocesses, namely a Sonogashira coupling followed by a tandem hydroxylation/cyclization sequence, give rise to new andinteresting dimethoxy-substituted benzo[b]furans.
