  吡咯霉素的全合成

  摘要：

  第一个分离出的大环内酯类抗生素吡咯霉素（6）的总合成得以实现。将目标大环内酯逆合成合成为两部分，吡克洛内酯（6a）（糖苷配基）和d-去糖胺。糖苷配基是使用关键反应合成的，例如不对称的醛醇缩合反应，山口酯化反应和闭环易位反应。在路易斯酸性条件下，将糖苷配基与d-去糖胺的三氯乙亚胺衍生物成功偶联，得到吡咯霉素。Narbomycin（5）也从narbonolide（合成5A）相同的条件下。

  Total Synthesis of (−)-4,8,10-Tridesmethyl Telithromycin

  摘要：

  Novel sources of antibiotics are required to address the serious problem of antibiotic resistance. Telithromycin (2) is a third-generation macrolide antibiotic prepared from erythromycin (1) and used clinically since 2004. Herein we report the details of our efforts that ultimately led to the total synthesis of (-)-4,8,10-tridesmethyl telithromycin (3) wherein methyl groups have been replaced with hydrogens. The synthesis of desmethyl macrolides has emerged as a novel strategy for preparing bioactive antibiotics.

  A highly convergent total synthesis of (+)-methynolide, based on two types of stereoselective aldol reaction, was achieved. The C1-C8 and C9-C11 fragments of (+)-methynolide were prepared by a vinylogous Mukaiyama aldol reaction using a vinyl ketene silyl N,O-acetal, and a Ti-mediated aldol reaction of a lactyl-bearing chiral oxazolidin-2-one, respectively.

  based on Cram chelation control. Ring-closing metathesis, as the key reaction, was carried out to combine the segments for the synthesis of methynolide and 10-epi-methynolide. The total synthesis of methymycin was also achieved by the glycosylation of methynolide with the trichloroimidate derivative of D-desosamine.

  There is an urgent need to discover new drugs to address the pressing problem of antibiotic resistance. Macrolide antibiotics such as erythromycin (1) are safe, broad spectrum antibiotics used in the clinic since 1954. Herein, we report the synthesis and evaluation of 4,8,10-tridesmethyl telithromycin (3), a novel desmethyl analogue of the third-generation drug telithromycin (2), which is a semisynthetic derivative of 1. Analogue 3 was found to possess antibiotic activity and was superior to telithromycin (2) when tested against resistant strains of Staphylococcus aureus possessing an A -> T mutation at position 2058 (Escherichia coli numbering).

  Novel sources of antibiotics are required to keep pace with the inevitable onset of bacterial resistance. Continuing with our macrolide desmethylation strategy as a source of new antibiotics, we report the total synthesis, molecular modeling, and biological evaluation of 4,10-didesmethyl telithromycin (4), a novel desmethyl analogue of the third-generation drug telithromycin (2). Telithromycin is an FDA-approved ketolide antibiotic derived from erythromycin (1). We found 4,10-didesmethyl telithromycin (4) to be four times more active than previously prepared 4,8,10-tridesmethyl congener (3) in MIC assays. While less potent than telithromycin (2), the inclusion of the C-8 methyl group has improved biological activity, suggesting that it plays an important role in antibiotic function.
