Diethyl 2-Acetamidomalonate, is a versatile building block used for the synthesis of various pharmaceutical and biologically active compounds. It is an intermediate for the preparation of Novobiocin analogues as potential heat shock protein 90 inhibitors. It is also used as a important intermediates in syntheses of vitamins B1 and B6, barbiturates, non-steroidal anti-inflammatory agents, other numerous pharmaceuticals.

Intermediate for synthesis of racemic amino acids, by reaction with an electrophile, e.g alkyl halide, followed by hydrolysis and decarboxylation. The reactivity can be reversed by conversion to the dehydro-derivative, which then undergoes nucleophilic attack with alkyllithiums, Grignards, malonate anion, etc.: Angew. Chem. Int. Ed., 21, 203 (1982):
Substituents can also be introduced by Michael addition to a wide variety of acceptors: Synth. Commun., 18, 367 (1988).
