摘要

-HC, syntheses are more useful for obtaining 3-carbonylpyrroles but less so for pyrrole-2- carboxylates. The above-described method allows us to obtain in a regioselective manner 3, 5-diarylpyrrole-2-carboxylates, whose difficult availability has already been reported, ll as well as 3-arylpyrrole-2-carboxylates, which are one of the most important intermediates for the synthesis of pyrrolnitrin. 12 The high yields obtained in all instances (see Table I) and ...
