hydroxylamidation with an oxidase/peroxidase-induced ene-type cyclization. This methodology provides a mild and scalable access to N-heterocyclic building blocks from basic γ,δ-unsaturated esters and aqueous hydroxylamine, and its utility is illustrated by the formal total synthesis of the tetracyclic alkaloid cephalotaxine.
N-羟基-γ-内酰胺是通过将脂肪酶催化的羟酰胺化与氧化酶/过氧化物酶诱导的烯型环化相结合的酶促序列来生产的。该方法提供了从碱性γ,δ-不饱和酯和水性羟胺中温和且可扩展地获得N-杂环结构单元的方法,其实用性通过四环生物碱头孢噻嗪的正式全合成得到了说明。
