Abstract: 2-Acetyl-3-amino-4-trifluoromethyl-6-substitutcdphenylfuro[2,3-b]pyridines are subjected to Claisen-Schmidth condensation with different arylaldehydes followed by intramolecular Michael type addition to obtain 4-oxo-1,2 ,3,4-tetrahydropyrido [3',2':4,5]furo[3,2-d] pyridines, a new tricyclic heterocyclic ring system of biological interest. The studies directed towards the synthesis of pyridofuropyrazoles have also been discussed.
