    future development of analogs with superior pharmacokinetics. We developed a robust approach to each of the key macrocyclic and sugar fragments, their union via stereoselective glycosylation, and a convergent late-stage macrolide formation with fully glycosylated fragments. Although we were able to demonstrate that the final Suzuki cross-coupling and ring-closing metathesis steps enabled macrocycle formation

    150, where a yield of >83% was obtained. The overall yields of the five-step procedure to 1,4-dideoxy-1,4-imino-l-lyxitol and 1,4-dideoxy-1,4-imino-d-lyxitol were 57% and 50%, respectively. This synthetic procedure has several advantages such as competitive overall yield, reduced number of steps, and mild reaction conditions. Furthermore, the zeolite catalyst can be easily recovered from the reaction
    由相应的d糖合成羟基吡咯烷,1,4-dideoxy-1,4-imino-l-lyxitol和1,4-dideoxy-1,4-imino-d-lyxitol的关键步骤是合成O-甲基2,3-O-异亚丙基戊烯呋喃糖酶。人们发现,采用沸石的多相催化可直接用于由d-糖直接合成O-甲基2,3-O-异亚丙基戊二酸呋喃糖酶,而不是采用传统的无机酸催化剂(如HCl和HClO4)进行均相催化过程,甲醇和丙酮在温和的条件下。最好的催化剂是Si / Al摩尔比为150的H-β沸石,其收率> 83%。对于1,4-二脱氧-1,4-亚氨基-1-糖醇的五步法的总产率分别为57%和50%。该合成方法具有许多优点,例如具有竞争力的总产率,减少的步骤数和温和的反应条件。此外,可以容易地从反应混合物中回收沸石催化剂,并在不损失活性的情况下对其进行再利用。
  • Syntheses of (−)-Oleocanthal, a Natural NSAID Found in Extra Virgin Olive Oil, the (−)-Deacetoxy-Oleuropein Aglycone, and Related Analogues
    作者:Amos B. Smith、Jeffrey B. Sperry、Qiang Han
    DOI:10.1021/jo071146k
    日期:2007.8.31
    Phenolic compounds extracted from extra virgin olive oil have attracted considerable recent attention. One of the components, (-)-oleocanthal (1), an inhibitor of the COX-1 and COX-2 enzymes, possesses similar potency as the NSAID ibuprofen. In this, a full account, we disclose the first- and now second-generation syntheses of both enantiomers of the oleocanthals, as well as the first synthesis of the closely related (-)-deacetoxy-oleuropein aglycone and a series of related analogues for structure activity studies. To demonstrate the utility of the second-generation synthesis, multigram quantities of (-)-oleocanthal were prepared in 10 steps (14% overall yield) from commercially available D-lyxose.
