One pot synthesis of pyridophenanthroline and pyrrolophenanthroline derivatives by regioselective reaction between 1,7-phenanthroline and dialkyl acetylenedicarboxylate: new fused heterocyclic compounds
1,7-Phenanthroline reacts with dialkyl acetylenedicarboxylate in a regioselective manner to give new macromolecules such as tetramethyl-6aH- pyrido[1,2-i][ 1,7] phenanthroline-7,8,9,10-tetracarboxylate and trialkyl pyrrolo[ 1,2-i][ 1,7] phenanthroline-7,8,9-tricarboxylate derivatives.
