A convenient tandem one-pot synthesis of donor–acceptor-type triphenylene 2,3-dicarboxylic esters from diarylacetylene

Abstract

A tandem one-pot method for the direct synthesis of polysubstituted triphenylene 2,3-dicarboxylic esters with different substitution patterns was developed by enyne metathesis of diarylacetylene, followed by Diels-Alder, aromatization and a cyclization cascade.
