摘要：
The present invention relates to a novel process for preparing cis-alkoxy-substituted spirocyclic phenylacetylamino acid esters and cis-alkoxy-substituted spirocyclic 1H-pyrrolidine-2,4-dione derivatives, and also to novel intermediates and starting materials which are produced and/or used in the process according to the invention.
