Two palladiumcatalyzed processes, namely a Sonogashira coupling followed by a tandem hydroxylation/cyclization sequence, give rise to new and interesting dimethoxy-substituted benzo[b]furans. eng http://creativecommons.org/licenses/by/2.0/ Este documento está sujeto a una licencia de uso Creative Commons, por la cual está permitido hacer copia, distribuir, comunicar públicamente, remezclar, transformar y crear a partir del material para cualquier finalidad, incluso comercial, siempre que se cite al autor original, se proporcione un enlace a la licencia y se indique si se han realizado cambios info:eu-repo/semantics/openAccess benzo[b]furans o-zincation palladium selectivity Combined directed ortho-zincation and palladiumcatalyzed strategies: Synthesis of 4,n-dimethoxysubstituted benzo[b]furans info:eu-repo/semantics/article
