Application

1-Methyl-2-pyrrolecarboxylic acid can be used as a reactant to prepare:
  • 1-Methyl-2-phenyl-1H-pyrrole by reacting with phenylbromide via palladium-catalyzed decarboxylative cross-coupling reaction.
  • 4,5-Diethyl-1-methylpyrano[3,4-b]pyrrol-7(1H)-one (a fused heterocycle pyrone) by ruthenium catalyzed oxidative coupling with 3-hexyne.

It can also be used for thermochemical and computational studies of 1-methyl-2-pyrrolecarboxylic acid.
