Participants

Reaction Steps

A 7.48 g. (17.6 mM) quantity of (αS,5S) 2-[(benzyloxy)carbonyl]-3-oxo-α-phthalimido-5-isoxazolidine acetic acid is dissolved in 150 ml. of ethyl acetate and 75 ml. of 95% ethanol. The solution is treated with 1.5 g. of palladium black and hydrogenated at 25° C. and 1 atmosphere of pressure. The reaction is stopped after 165 minutes, filtered, and the filtrate is evaporated in vacuo to yield 3-oxo-α-phthalimido-5-isoxazolidine acetic acid as a residue.
