The crystal structure and the conformation of the title compound, C22H27N3O7S, were determined from the synthetic pathway and by X-ray analysis. This compound is a new 4-thiazolidinone derivative prepared and isolated as pure product from thiosemicarbazone carvone. The molecule is built up from an oxothiazolidine ring tetrasubstituted by a methoxy–oxoethylidene, a maleate, an oxygen and a cyclohexylidene–hydrazone. The cyclohexylidene ring is statistically disordered over two positions, resulting in an inversion of configuration for the substituted carbon.
