In the title compound, C(27)H(26)N(2)O(6), the imidazolidine ring adopts an envelope conformation. The methyl group on the imidazolidine ring is disordered over two positions with occupancies of 0.517 (11) and 0.483 (11), and the 3,4-methyl-enedioxy-phenyl at the 3-position of imidazolidine ring is also disordered over two positions with occupancies of 0.60 (2) and 0.40 (2).
The title compound, C(16)H(26)ClNO(3) contains one almost planar furan-one ring [maximum deviation of 0.021 (2) Å for the O atom] with a stereogenic center (S) and one cyclo-hexane ring which displays a chair conformation and has three stereogenic centers [S at the C atom bearing the isopropyl group, R at the C atom attached to the O atom and R at the C atom bearing the methyl group].
