2-Cyano-2-phenylpropionic acid

Conversion of (S)-2-cyano-2-methyl-3-phenylpropionic acid (6) to (S)-a-methylphenylalanine (7) through the Hofmann and Curtius rearrangements followed by hydrolysis also proceed with nearly complete retention of configuration (equation 8). ... [Pg.799]

The decarboxylation of 2-cyano-2-phenylpropionic acid 20, a model compound of 14 was also investigated by the same authors [14]. While cinchonine 8 provided (S)-2-phenyl propionitrile 21 in only 13% ee, 9-ept-cinchona-benzamides 19b and 18b confirmed their superiority over the parent cinchona alkaloids affording 21 with up to 61% ee (Scheme 3.7). [Pg.74]
