Di-tert-butyl 2-[[[2-(benzylcarboxy)propyl]tert-butoxyphosphinyl]methyl]pentanedioate → Di-tert-butyl 2-[[[2-(carboxy)propyl]tert-butoxy-phosphinyl]methyl]pentanedioate

Participants

Reaction Steps

A solution of di-tert-butyl 2-[[[2-(benzylcarboxy)propyl]tert-butoxyphosphinyl]methyl]pentane1,5-dioate (8.9 g, 16.1 mmol), palladium on carbon catalyst (10%, 1.0 g) and ethyl acetate (100 mL) was shaken under hydrogen (60 psi) for 16 hours. The reaction mixture was filtered over celite and the filtrate was concentrated under reduced pressure leaving a clear oil (7.5 g, 100%).
