A-Acetoaminocinnamic acid

Asymmetric hydrogenation of a-amidoacrylic acids and related olefins has been reported to proceed with high enantioselectivity in the presence of chiral ferrocenyl-phosphine-rhodium catalysts. Both ferrocenylmonophosphines [21, 24, 58] and ferrocenylbisphosphines [17, 59, 60] can produce A -acetylphenylalanine with >80 /o ee in the rhodium-catalyzed hydrogenation of a-acetoaminocinnamic acid or its esters (Scheme 2-42). The high selectivity is ascribed mainly to a characteristic structure of the olefinic substrate that has an amido group at the proper position... [Pg.128]
