    Novel Synthesis of l-Ribose from d-Mannono-1,4-lactone
    摘要:
    [GRAPHICS]D-Mannono-1,4-lactone was efficiently converted into L-ribose in eight steps. A key step of this synthesis is the cyclization of a gamma-hydroxyalkoxamate under Mitsunobu conditions. It is noteworthy that the O-alkylation product was obtained in 94% yield and that none of the N-alkylation product was detected in this cyclization.

    Gram-negative bacteria, which has been validated as antibacterial drug target. Herein we report the chiral-pool synthesis of novel d- and l-proline-derived 3,4-dihydroxypyrrolidine hydroxamates and compare their antibacterial and LpxC inhibitory activities with the ones of 4-monosubstituted and 3,4-unsubstituted proline derivatives. With potent antibacterial activities against several Gram-negative pathogens,
    依赖Zn2 +的脱乙酰基酶LpxC是革兰氏阴性细菌中必不可少的酶,已被确认为抗菌药物的靶标。本文中,我们报道了新颖的d和l-脯氨酸衍生的3,4-二羟基吡咯烷异羟肟酸酯的手性池合成,并将它们的抗菌和LpxC抑制活性与4-单取代和3,4-未取代的脯氨酸衍生物进行了比较。具有对几种革兰氏阴性病原体的有效抗菌活性,基于脯氨酸的叔胺41g((S)-N-羟基-1-(4-[4-(吗啉代甲基)苯基]乙炔基}苄基)吡咯烷-2 (羧酰胺)被发现是所研究系列中最具活性的抗菌化合物,对几种人类MMP表现出对EcLpxC(Ki = 1.4μM)的选择性。

The relief of the conformational strain leading to the respective open chain derivatives generally caused an increase in the inhibitory and antibacterial activities of the benzyloxyacetohydroxamic acids. With Ki-values of 0.35 μm and 0.23 μm, the (S,S)-configured open-chain derivatives 8b and 8c were found to be the most potent LpxC inhibitors of these series
    细菌脱乙酰基酶LpxC的抑制剂已成为一种有希望的新型革兰氏阴性选择性抗菌剂。为了找到新颖的LpxC抑制剂,在从d-甘露糖开始的手性池合成中,以立体化学纯的形式制备了在四氢呋喃环的2和/或5位具有改变构型的C-呋喃糖苷。另外,四氢呋喃环的3和4位的取代方式以及2位的亲脂性侧链的结构也不同。最后,通过适当保护的C-糖苷的二醇裂解获得各个开链二醇的所有立体异构体。 合成的异羟肟酸的生物学评估表明,在使用C-糖苷的情况下,2,5-反式构型通常会导致优异的抑制和抗菌活性。导致各自的开链衍生物的构象菌株的释放通常引起苄氧基乙氧基异羟肟酸的抑制和抗菌活性增加。具有K我-值的0.35μ米和0.23μ米,则(小号,小号) -构型的开链衍生物8B和8C被发现是这些系列的化合物的最有力的LpxC抑制剂。

    α-bromoisobutyrate allowed the synthesis of ulosonic acid esters, which were readily transformed into the corresponding tetrahydrofuran β-azido esters in a stereoselective fashion. This approach provided monomeric components suitable for oligomerization to the carbopeptoid class of foldamers and prompted the total synthesis of the attractive novel spiro diketo-piperazine, which can be regarded as a

    the desired C-glycosides was achieved by a Mitsunobu reaction or by preparing the 1-O-benzoyl-4-O-methylsulfonyl derivative 7 which was then treated with sodium methoxide. Final hydrolysis of the 5,6-O-isopropylidene protecting group led to the diastereomeric diols (1S,4R)-4a, (1S,4S)-4b, (1R,4R)-4c, and (1R,4S)-4d, representing versatile building blocks for further synthetic transformations.
