The X-ray structure of the sulfone 38 was inadvertently shown with the incorrect absolute configuration in Fig. 9 in the original manuscript. The corrected Fig. 9 is shown below, along with corrected note 59. Additionally, the original CIF file for the structure of the sulfone 38 contained an error. The corrected CIF file has since been deposited at the CCDC (Deposit-698760-corrected).†

59. Crystal structure determination: Crystallographic data of sulfone 38 was collected on the synchrotron radiation source at Station 9.8, Daresbury SRS, UK, on a Bruker SMART CCD diffractometer. The structures were solved by direct methods using the program SIR92 (ref. 65). The refinement (on F) and graphical calculations were performed using the CRYSTALS (ref. 66) program suite. Crystal data: C15H20O5S, M = 312.39, Z = 4, monoclinic, space group P21, a = 5.5615(17) Å, b = 27.699(8) Å, c = 10.094(3) Å, β = 105.644(6)º, V = 1497.4(8) Å3, T = 150 K, μ = 0.235 mm-1. Of 10048 reflections measured, 6771 were independent (Rint = 0.028). Final R = 0.0528 (5013 reflections with I > 2σ (I)) and wR = 0.1102. Crystallographic data (excluding structure factors) for this structure have been deposited with the Cambridge Crystallographic Data Centre as supplementary publication no. CCDC 698760-corrected.
