—— | (S)-2-(4-toluenesulfonylamino)-5-(2-iodophenyl)pent-4-ynoic acid methyl ester | 869115-92-4 | C19H18INO4S | 483.327 |
Two complementary strategies for the synthesis of optically active fluorine-containing building blocks have been probed. The first strategy involves either the enzymatic resolution of fluorinated ?,?-disubstituted-?-amino acid amides, or the asymmetric hydrogenation of fluorinated dehydroamino acids. The second strategy involves the transition metal-catalyzed introduction of fluorine-containing substituents onto olefin- or acetylene-containing ?-H-?-amino acids. These amino acids in turn are made optically active by enzymatic resolution of the corresponding amides.
