New pyrazolo[4′,3′:5,6]pyrido[2,3‐ d ]pyrimidines, with an associated spiro‐3,3′‐oxindole attachment, were prepared by three‐component combinations of 5,6‐dihydro‐4 H ‐pyrrolo[3,2,1‐ ij ]quinoline‐1,2‐dione with a pair of reactants chosen from a pyrazol‐5‐one, a pyrazole‐5‐amine, a barbituric acid, or a 6‐aminouracil.
