    • 2O (0.8 mol%) was critical for AD reactions of β,γ-unsaturated phosphonates since the AD reaction of 2b in the absence of the osmium salt resulted in slow reaction rates (20 h at 25 °C) and slight decrease in enantioselectivity (54% yield, 30% ee).

    • Kobayashi and co-workers observed that a related AD of α-olefins with dibenzyl phosphonate showed higher enantioselectivity than the corresponding diethyl phosphonate. See: Kobayashi, Y.; William, A. D.; Tokoro, Y. J. Org. Chem. 2001, 66, 7903.

    • 3) of 13, a signal ascribed to the Me group at the γ-position was observed at δ = 1.18 ppm as a doublet (J = 7.1 Hz) but not as a singlet corresponding to regioisomeric β-amino-γ-ketophosphonate (Scheme 7). (Diagram presented)
