    • Initial experiments indicated that the low solubility of 13 in the aqueous reaction medium posed difficulties in accurate sampling for analysis by chiral-phase HPLC. On the other hand, complete extractions of reaction mixtures provided >90% mass recovery. Parallel reactions were therefore started simultaneously, and then each reaction mixture was extracted completely after a given period of time. All samples were analyzed by chiral-phase HPLC, which cleanly resolved 13 and the four possible reduced products.

    • Analytical samples were prepared by vortexing 0.5 mL of the reaction mixture with 0.5 mL of EtOAc. After the mixture was centrifuged at 7500 rpm for 1 min, the organic layer was removed, filtered, and analyzed by HPLC.
