Regioselective Synthesis of Highly Aryl‐Substituted Pyrrole Carboxylates as Useful Medicinal Chemistry Leads
摘要:
The regioselective syntheses of two pharmaceutically relevant pyrrole scaffolds are described. A synthetic route for the preparation of differentially substituted pyrrole-3,4-dicarboxylates is presented and exemplified. This route circumvents some of the problems and limitations associated with previous butynedioic diester condensations and 1,3-dipolar cycloaddition reactions. A route to the related 4,5-diarylpyrrole2-carboxylic acid scaffold is also presented. Both routes allow for the regiocontrolled preparation of highly substituted pyrrole pharmacophore cores.
