Abstract: cis-8-Methoxy-1,3-diazaspiro[4.5]decane-2,4-dione, the key intermediate in the synthesis of spirotetramat, was synthesized by catalytic hydrogenation, oxidation, and Bucherer–Bergs reaction with 4-methoxycyclohexan-1-one as raw material. Spirotetramat was obtained in an overall yield of 20.4% by a multi-step reaction sequence including hydrolysis, esterification, acylation, intramolecular condensation, and O-acylation. The advantages of the proposed method are mild conditions, simple operation, and good to excellent yields in each step.
