In the paper by Wang et al. (2010) ▶, 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.
