The absolute configuration in the title of the paper by Wang, Zhang, Xu & Zhang [Acta Cryst. (2010), E66, o217] is corrected.

In the paper by Wang et al. (2010)[Wang, Y., Zhang, W., Xu, X. & Zhang, G. (2010). Acta Cryst. E66, o217.], the chemical name given in the Title should be `(2R,4R)-Ethyl 4-(4-chloro­phen­yl)-2-hydr­oxy-5-oxo-2,3,4,5-tetra­hydro­pyrano[3,2-c]chro­mene-2-carboxyl­ate'. The absolute configuration was established by anomalous-dispersion effects in diffraction measurements on the crystal. The revised scheme is shown below.
