The steps in the synthesis of valine from diethyl acetamidomalonate are to be outlined. A reason for the low yield of about 31 % for this method is to be given. Concept Introduction: The hydrogen bonded to the carbon between the two ester groups of diethylmalonate is acidic because of the adjacent electron withdrawing groups. Deprotonation with a strong base such as an alkoxide generates a carbanion which can act as a nucleophile.
