Synthesis of (-)-tabtoxinine-β-lactam and its (3R)-isomer, the cause of tobacco wildfire disease, was achieved from l-serine using a zinc-mediated coupling reaction, Sharpless asymmetric dihydroxylation and lactamization of β-mesyloxy benzylhydroxamate amide as the key steps.
以 l-丝氨酸为原料,通过锌介导的偶联反应、Sharpless 不对称二羟基化反应和 δ-甲酰氧基苄基羟酰胺内酰胺化反应等关键步骤,合成了烟草野火病的致病物 (-)-tabtoxinine δ-内酰胺及其 (3R) 异构体。
