The rates of base-catalyzed hydrolysis of pseudo esters derived from y-keto acids show strikingly poor sensitivity to the nature of the leaving group.la The rates vary in the narrow range of about 12-fold as contrasted to a 103-fold spread of the corresponding benzoate esters. The results pr...
acetyl or benzoyl, derivatives of alphaamino-gamma-keto acids, which are new compounds. The method comprises adduct formation between a primary amide and glyoxylic acid or esters thereof and the subsequent reaction of the said adduct with 1, 3 dicarbonyl compounds in the presence of an acid ...
The cause of rate enhancement in carbonyl-assisted hydrolysis and in greater detail the case of 6-substituted derivatives are discussed. It is shown that the carbonyl-assisted hydrolyses are characterized by decreased sensitivity to leaving-group structure. The implications of this result are pointed ...

Halogenated products of the process as well as ammonia and amine salts of the acids made by the process are useful as insecticides, plant grown control agents and defoliants. Particularly useful products are those olefinic polychlorinated derivatives of gamma-keto-pentanoic acid which contain at ...
