4-Cyanobutanoic acid

The pA of 3-cyanobutanoic acid is 4.44. Using the pAT values of chlorine-substituted butanoic acids as a guide, estimate the pAf of 2-cyanobutanoic acid. [Pg.692]

Selective reduction of 3-cyanobutanoic acid can give either 4-aminobutanoic acid or 4-cyano-l-butanol. Describe spectroscopic differences in these molecules that will allow you to distinguish them and determine the identity of... [Pg.1417]

An approach that was not very successful saw a carbamate isoasparagine derivative (1.236) converted to a nitrile via dehydration of the amide moiety. Removal of the protecting group gave 3-amino-3-cyano-propanoic acid (7.237). This approach was also used to prepare 4-amino-4-cyanobutanoic acid, but the yield of amino acid was again very poor. Introduction of a cyano group in this particular way does not appear to be a good synthetic procedure. [Pg.44]
