Catalytic transformation of serine-O-carbonate to S-aryl cysteine derivatives was successfully achieved in the presence of Li+ by the use of a pyridoxalmodelcompoundhaving an ionophore function, which is the first example mimicking cystathionine β-synthase, artificially.
Serine-O-carbonate derivatives, including peptides having a serine-O-carbonate residue at the N-terminal position, are catalytically transformed into S-substituted cysteine derivatives employing the pyridoxal model having an ionophore function in the presence of Li+; this is the first artificial model mimicking cystathionine β-synthase.
丝氨酸-O-碳酸酯衍生物,包括在 N 端位置具有丝氨酸-O-碳酸酯残基的肽,在 Li+ 的存在下,利用具有离子发酵功能的吡哆醛模型,催化转化为 S-取代的半胱氨酸衍生物;这是第一个模拟胱硫醚合成酶的人工模型。
