A simple, economical, and green approach to the one‐pot synthesis of 3‐methyl‐4‐aryl‐2,4,5,7‐tetrahydropyrazolo[3,4‐ b ]pyridine‐6‐ones by multicomponent assembling of 5‐methylpyrazol‐3‐amine, aldehydes, and Meldrum's acid using sodium dodecyl sulfate as surfactant in water is described. This protocol has the advantages of high yields, wide application scope, and an environmental benign procedure.
