K. Araki et al., EFFICIENT LANTHANIDE CATALYSIS IN AMINOACYL-TRANSFER FROM THE BIPYRIDINE-FUNCTIONALIZED AMIDE-SUBSTRATE TO ALCOHOLS AT AMBIENT-TEMPERATURE, Chemistry Letters, (4), 1996, pp. 295-296
Lanthanide cations showed high catalytic activities in aminoacylation
of alcohols by the amide-substrates having bipyridine as a metal chela
tion site at 30 degrees C (first-order rate constants were 10(-4) s(-1
) range at Ce3+/substrate = 0.2), yielding corresponding amino acid es
ters almost quantitatively.
