  Synthesis and structure of cyclic phosphopeptides containing a phosphodiester linkage

  摘要：

  The synthesis of three cyclic phosphopeptides, which contain a phosphodiester linkage, is described. Starting from either Boc-L-Ser(OBn)-OH or BOC-L-Thr(OBn)-OH, three precursors for the macro-cyclization by phosphitylation were prepared. After phosphitylation, using 4-chlorobenzyl bis(N,N-diisopropylamino)phosphinite or 4-chlorobenzyl dichlorophosphinite, subsequent oxidation and hydrogenolysis the cyclic phosphopeptides 18-20 were obtained. The solution conformation of cyclic phosphopeptide 18 was studied by NMR spectroscopy and restrained molecular dynamics calculations.

  The selective cleavage of thermodynamically stable C(sp3)−C(sp3) single bonds is rare compared to their ubiquitous formation. Herein, we describe a general methodology for such transformations using homogeneous copper‐based catalysts in the presence of air. The utility of this novel methodology is demonstrated for Cα−Cβ bond scission in >70 amines with excellent functional group tolerance. This transformation

  与它们普遍存在的形成相比，热力学稳定的C（sp 3）-C（sp 3）单键的选择性裂解是罕见的。本文中，我们描述了在空气存在下使用均相铜基催化剂进行此类转化的一般方法。这种新颖的方法的效用证明对C α -C β在> 70度胺具有优良的官能团耐受性键断裂。该转化建立了叔胺作为酰胺的一般合成子，并为其在例如天然产物和生物活性分子中的可扩展功能化提供了宝贵的可能性。

  Herein, a metal-free strategy for the aerobic oxidative cleavage of the inert C(sp3)−C(sp3) bond was developed. Deconstruction of morpholine derivatives was conducted using visible light as an energy source and O2 as an oxidant under mild conditions. This procedure demonstrated suitable selectivity and functional group tolerance. Moreover, a possible mechanism involving a radical process was proposed
