Development of the total syntheses of arylomycins A1 and B2 is detailed. Key features of our approach include 1) formation of 14‐membered meta,meta‐cyclophane by an intramolecularSuzuki–Miyaurareaction; 2) incorporation of N‐Me‐4‐hydroxyphenylglycine into the cyclization precursor, which avoids the late‐stage low‐yielding N‐methylation step; 3) segment coupling of a fully elaborated peptide side
详细介绍了arylomycins A 1和B 2的总合成过程。我们方法的主要特征包括:1)通过分子内Suzuki-Miyaura反应形成14元间位,间环烷;2)将N -Me-4-羟基苯甘氨酸掺入环化前体中,避免了后期的低产N-甲基化步骤;3)将完整加工的肽侧链与大环段偶联,从而使合成高度收敛。总体而言,芳基霉素A 2以最长的线性序列从L- Tyr以13个步骤获得,总产率为13%。阿霉素B 2从L -3-硝基Tyr分十步合成,总收率为10%。

simple C–H functionalization logic that is enabled by a Cu-mediated oxidative phenol coupling that mimics the putative biosynthesis. This operationally simple macrocyclization is the largest of its kind and can be easily performed on gram scale. The application of this new route to a formal synthesis of the natural product and a collection of new analogues along with their biologicalevaluation is also
Arylomycins 是一类有前途的“潜在”抗菌天然产物,目前处于临床前开发阶段。获得该家族内的类似物以前需要一条涉及多个官能团操作的冗长途径,这在规模上是昂贵且耗时的。该研究提出了一种基于简单 C-H 功能化逻辑的简化路线,该逻辑由模拟假定生物合成的 Cu 介导的氧化苯酚偶联启用。这种操作简单的大环化是同类中最大的,并且可以很容易地在克规模上进行。还报告了这种新途径在天然产物的正式合成和新类似物集合及其生物学评价中的应用。
