  Synthesis of Muramyl Peptides Containing meso-Diaminopimelic Acid

  摘要：

  Chain-extension Of L-glutamate aldehyde 3 by means of the Wittig-Homer reaction furnished the desired C-7 dicarboxylic acid derivative, which in turn, after C-C double bond hydrogenation and protecting group manipulation, afforded the 2,6-diaminopimelic acid derivatives (S,R)-9 and (S,S)-9, both with the desired orthogonal protecting group pattern. Synthesis of the muramic acid derivative 15 and attachment of an L-alanine residue furnished muramyl-L-alanine 18. The corresponding 1,6-anhydromuramic acid derivative 26 was obtained similarly. Treatment of these compounds with peptides 28-30 and with the 2,6-diaminopimelic acid containing di- and tripeptides 32a, 32b, and 35 gave the protected muramyl peptides 17, 37, 40, 42, 44, 46, and 49a and 49b, which, after deprotection, afforded the desired target molecules muramyl-L-alanine (38), muramyl-L-alanyl-D-glutamic acid (39), muramyl-L-alanyl-D-glutaminide (41), muramyl-L-alanyl-D-isoglutaminyl-L-lysine (43), muramyl-L-alanyl-D-isoglutaminyl-(2S,6R)-2,6-diaminopimelic acid (45), muramyl-L-alanylL-isoglutaminyl-(2S,6R)-2,6-dian-Anopimelinyl-D-alanine (47), 1,6-anhydromuramyl-L-alanyl-D-isoglutaminyl-(2S,6R)-2,6-diaminopimelic acid (50a), and 1,6-anhydromuramyl-L-alanyl-Disoglutaminyl-(2S,6S)-2,6-diaminiopimelic acid (50b).

  Our amide-linked C-glycosyl amino acids and peptides are synthesized through cooperative Ni-catalyzed and photoredox processes. The catalytic process generates a glycosyl radical and an amide carbonyl radical, which subsequently combine to yield the C-glycosyl products. The saccharide reaction partners encompass mono-, di-, and trisaccharides. All 20 natural amino acids, peptides, and their derivatives

  糖蛋白负责许多生物过程，包括与疾病和感染相关的生物过程。糖肽的进步已成为解开生物途径和发现新药物的有前途的策略。在这个领域，一个关键的挑战是缺乏有效的合成策略来获取糖肽和糖蛋白。在这里，我们提出了一种通过酰胺键将糖与氨基酸和肽桥接的高度简洁的方法。我们的酰胺连接C-糖基氨基酸和肽是通过镍催化和光氧化还原过程协同合成的。催化过程产生糖基自由基和酰胺羰基自由基，它们随后结合产生C-糖基产物。糖反应伴侣包括单糖、二糖和三糖。所有 20 种天然氨基酸、肽及其衍生物都可以有效地进行糖基化，产率从可接受到高不等，表现出优异的立体选择性。作为应用的实质性扩展，我们已经证明简单的C-糖基氨基酸可以作为通用的构建单元来构建具有复杂空间复杂性的C-糖肽。
• Cross‐metathesis of<i>C</i>‐Glycosides and Peptides

  Peptides bearing an acryloyl residue at their N-terminus were coupled with various C-glycosides in an equimolar ratio via cross-metathesis. The newly formed olefin was obtained with high E/Z selectivity in satisfying to high yields with low homodimerization of the starting materials. The posttranslational cross-metathesis approach was shown to be suitable for the combinatorial synthesis of a small library of C-glycopeptides.
