Heterocyclic compounds containing pyrrole and indole-fused isocoumarins were obtained from a one-pot synthesis via annulations of N-heterocyclic carboxylic acids and alkynes with N^O chelate ruthenium(II)complex, [RuCl(PySO3)(p-cymene)] (PySO3 = 2-pyridinesulfonate) in the presence of Cu(OAc)2H2O. The reaction proceeds efficiently in DMF but can also be performed in other solvents such as dichloroethane, tAmOH, and water. The annulations reaction is regioselective when performed 1-methylpyrrole-2-carboxylic acid with 1-phenyl-1-propyne.
