Hetarylation of 1-methylpyrrole by isoquinoline in the presence of aromatic or aliphatic sulfonyl chlorides

When N-alkyl(or aryl) sulfonylisoquinolinium salts are reacted in situ with 1-methylpyrrole, 2-aryl (or alkyl) sulfonyl-1-(pyrrole-2-yl)-1,2-dihydroixoquinolines and 2,5-di[2-aryl(or alkyl)-sulfonyl-1,2-dihydroisoquinolin-1-yl]-1-methylpyrroles form with high yields.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1379–1382, October, 1984.
