bond formation step involved in penicillin biosynthesis is peroxide, thus, oxidation of a monocyclic β-lactam thiol, or its disulphide form, with dioxygen or hydrogen peroxide, catalysed by iron(II) ion, ascorbic acid and ethylenediaminetetra-acetic acid, results in direct ring closure to penicillins as well as cephams, in a process similar to the enzymatic synthesis.
青霉素生物合成中碳硫键形成步骤的有效化学模型是过氧化物,因此,铁(II)离子催化的二氧或过氧化氢可氧化单环β-内酰胺硫醇或其二硫键形式的抗坏血酸乙二胺四乙酸和乙二胺四乙酸导致青霉素和头孢菌素的直接闭环,其过程类似于酶促合成。
