A new method is reported for the conversion of azido acids into lactams, via thioester formation and in situ azide reduction and cyclisation under high-dilution conditions; since the quantitative conversion of macrolactams to macrolactones has been shown to be feasible, this results in an indirect, alternative macrolactonisation procedure.
据报道,有一种新方法可以在高稀释条件下,通过硫酯的形成,叠氮化物的原位还原和环化作用,将叠氮基酸转化为内酰胺。由于已经证明大内酰胺向大内酯的定量转化是可行的,因此这导致了间接的替代大内酯化过程。
