One pot synthesis of terpyrromethanes (3a) and [di(1H-pyrrol-2-yl)methyl]heteroarenes (3b-m) has been delineated by Amberlyst 15 catalyzed condensation of pyrrole and heterocyclic aldehydes (2), not reported earlier. The compounds 3a and 3b have been formylated to 5-[di(5-formyl-1H-pyrrol-2-yl)methyl]-1H-pyrrole-2-carbaldehyde (4a) and 5[(5-formyl-1H-pyrrol… CONTINUE READING
