relationship between structural and antitumor activity, α-acetylamino acids containing a terminal methyleneketo group (namely, 2-acetamido-5-oxo-6-heptenoic acid, and 2-acetamido-4-oxo-5-hexenoic acid) and related derivatives have been synthesized. Their structures were confirmed by a study of their chemical reactions and their ultraviolet and infrared absorption spectra. It has been found that methyl esters
