The first synthesis of auxofuran, a newly discovered auxin-like signaling molecule of streptomycetes, has been achieved in seven steps and 59% overall yield from commercial starting materials. Central to the synthetic route is a click–unclick Diels–Alder cycloaddition/cycloreversion regimen enabling rapid access to an advanced intermediate from an unactivated alkyne.
新发现的链霉菌生长素样信号分子auxofuran的第一个合成已通过七个步骤完成,并从商业原料中获得了59%的总收率。合成路线的中心是单击-取消Diels-Alder环加成/环还原法,可从未活化的炔烃快速进入高级中间体。
