Abstract

Two-directional annulation of dibromoisobenzofuran,a formal equivalentto didehydroisobenzofuran, was developed. Importantly, selective bromine–lithiumexchange allows the tandem generation of benzynes and dual cycloadditionswith two different arynophiles. Also described is the applicationto the synthesis of a substituted pentacene. [ABSTRACT FROM AUTHOR]
