If the alkyl group of a /3-alkyl-/3-phenyl-a,c/-dicyanoglu-tarimide is larger than the methyl group, the hydrolysis to the corresponding glutaric acid should be modified as described by McElvain and Clemens, J. Am. Chem. Soc., 80, 3915 (1958). 

Glutaric acid, 30, 48 i8, 8-dimethyl-, 31, 40 3-ETHYL-3-METHYL-, 36, 28 Glutaric anhydride, ck-phenyl, 30, 81 Glycerol, 32, 72... 

It is interesting to note that in fermented products the same alcohols always form, even if different sources of nitrogen, but not singular aminoacids, are available. Ketoacids can also be directly reduced to hydroxyacids such as lactic, 2-hydroxy-3-methyl butyric, 2-hydroxy-3-methyl pentanoic, 2-hydroxy-4-methyl pentanoic, 2-hydroxy-3-phenyl propionic and 2-hydroxy glutaric acids. The corresponding ethyl esters can dramatically influence the wine aroma.
