N. Sewald et al., ALPHA-TRIFLUOROMETHYL SUBSTITUTED ALPHA-AMINO-ACIDS AND ALPHA-HYDROXYACIDS WITH ORGANOMETALLIC MOIETIES IN THE SIDE-CHAIN, Heteroatom chemistry, 4(2-3), 1993, pp. 253-258
Several strategies for the synthesis of alpha-trifluoromethyl substitu
ted alpha-aminoacids and alpha-hydroxyacids with organometallic moieti
es in the side chain are described. The preparative potential of organ
ometallic substituents (organosilicon, organotin, and organocobalt moi
eties) offers a convenient methodology for the synthesis of highly fun
ctionalized alpha-aminoacid and alpha-hydroxyacid derivatives.
