A facile, atom-economical, and one-pot pseudo four-component method for the synthesis of isoxazolylspiro[diindeno[1,2-b;2,1-e]pyridine-11,3-indoline]-2,10,12-trione derivatives (14) is described. Prominent advantages of this new method are operational simplicity, excellent yields with high purity, short reaction time, easy workup, and mild conditions.
