通过高效的3 -或4 -原子迭代扩环工艺,内酰胺和羟基酸衍生物可以制备大环内酯。产品也可以使用基于氨基酸的线性片段进行扩展,这意味着具有精确羟基和氨基酸序列的大环可以通过从较小的环“生长”而高产量地组装,使用简单的程序,不需要高度稀释。该方法应显著加快实际合成各种含氮大环内酯框架。
Macrocyclic lactones can be prepared from lactams and hydroxyacid derivatives via an efficient 3‐ or 4‐atom iterative ring expansion protocol. The products can also be expanded using amino acid‐based linear fragments, meaning that macrocycles with precise sequences of hydroxy‐ and amino acids can be assembled in high yields by “growing” them from smaller rings, using a simple procedure in which high dilution is not required. The method should significantly expedite the practical synthesis of diverse nitrogen containing macrolide frameworks.
