The rate at which Cr+2 reacts with a variety of half-ester complexes of fumaric acid is not very different from the rate at which it reacts with the fumaric complex. Thus, the specific rates for the methylfumarate (20), phenylfumarate (9), and fumaric acid (20) complexes are 1.4, 1.5, and 1.3 respectively. However, when... [Pg.112]

The hydrogenation of jS-acetamidoacrylates has also been achieved under similar conditions to give /3-amino-acid derivatives of ca. 55% optical purity. An example of chiral induction at two adjacent carbon atoms is the hydrogenation of dimethyl (Z)-2-acetamido-3-methylfumarate, in the presence of a chiral cationic pyrrolidine-phosphine Rh complex, which leads to (2R,3R)-/3-methyl-aspartic acid of about 55% enantiomeric enrichment. Studies of the mode of action of the aforementioned catalyst have been carried out and a flexible synthesis of functionalized chelating diphosphines has been described. ... [Pg.128]
