HETARYLATION OF 1-METHYLPYRROLE BY ISOQUINOLINE IN THE PRESENCE OF AROMATIC OR ALIPHATIC SULFONYL CHLORIDES
Sheinkman, A. K.,Sidorenko, L. M.,Skrypnik, Yu. G.
, p. 1136 - 1139 (2007/10/02)
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-dihydroisoquinolines and 2,5-di-1-methylpyrroles form with high yields.
