Reaction Steps

Butyl[2,4-di(benzyloxycarbonyl)butyl]phosphinic acid (2.9 g, 6.5 mmol) in 30 mL of water containing 0.32 g 10% Pd/C was hydrogenated at 40 psi for 4.5 hours. The mixture was filtered through a pad of Celite and evaporated under high vacuum to give 2-[(butylhydroxyphosphinyl)methyl]-pentanedioic acid (4, R=n-butyl) (0.75 g, 43%) as a clear and colorless viscous oil.
