Reaction Steps
Compound (S)-10a was synthesized by a procedure similar to that described for (R)-10a using (Z)-tert-butyl(1-(3-chlorophenyl)prop-1-enyloxy)dimethylsilane (9a, 8.8 g, 0.031 mol), AD-mix-α (43.5 g), and CH3SO2NH2 (3a, 3 g, 0.032 mol) in tert-butyl alcohol-water (120 mL:120 mL). The reaction mixture was quenched with sodium sulfite (31.1 g). After purification, 4.51 g (78%) of the (S)-10a was isolated. Characterization data is similar with data reported in Fang, Q. K.; Han, Z.; Grover, P.; Kessler, D.; Senanayake, C. H.; Wald, S. A., Tetrahedron: Asymmetry 2000, 11, 3659-3663.
