Lanthanide cations showed high catalytic activities in aminoacylation of alcohols by the amide-substrates having bipyridine as a metal chelation site at 30 °C (first-order rate constants were 10−4 s−1 range at Ce3+/substrate = 0.2), yielding corresponding amino acid esters almost quantitatively.
在 30 °C 下,以联吡啶作为金属螯合位点的酰胺底物对醇进行氨酰化时,镧系阳离子表现出较高的催化活性(Ce3+/底物 = 0.2 时,一级速率常数为 10−4 s−1 范围),产生相应的氨基酸酯几乎定量。
