Amines also react with P-keto-esters to give the corresponding amino acid derivative. When 1.133 was treated with ethylamine in reaction 4, ethyl 3-(N-ethyl-amino)-3-phenylprop-2-enoate (1.134) was obtained. Several other 3-aryl derivatives (piperonyl, p-bromophenyl, p-methylphenyl, and p-nitrophenyl) were prepared by this method. The use of different amines (methylamine, isopropylamine, benzyl-amine, allylamine, aniline) led to several different N-substituted derivatives. ...
