    摘要:
    基于多米诺迈克尔加成/腈氧化物形成/[3+2]环加成方法描述了新的杂环异恶唑啉氨基酸的合成。螯合氨基酸酯烯醇化物可加入硝基烯烃,生成的硝基酸酯直接转化为氧化腈。这些可以通过作为偶极体的烯烃在分子内捕获。烯烃可以通过硝基烯烃或通过螯合的烯醇化物引入。因此,可以通过简单的一锅程序获得不同类型的杂环氨基酸。

  • The Continuous Acid-Catalyzed Dehydration of Alcohols in Supercritical Fluids:  A New Approach to the Cleaner Synthesis of Acetals, Ketals, and Ethers with High Selectivity

    We report a new continuous method for forming ethers, acetals and ketals using solid acid catalysts, DELOXAN ASP or AMBERLYST 15, and supercritical fluid solvents. In the case of ether formation, we observe a high selectivity for linear alkyl ethers with little rearrangement to give branched ethers. Such rearrangement is common in conventional syntheses. Our approach is effective for a range of n-alcohols
    我们报告了一种使用固体酸催化剂、DELOXAN ASP 或 AMBERLYST 15 和超临界流体溶剂形成醚、缩醛和缩酮的新连续方法。在醚形成的情况下,我们观察到线性烷基醚的高选择性,很少重排得到支链醚。这种重排在常规合成中很常见。我们的方法对一系列正辛醇和仲醇 2-丙醇均有效。在苯酚与烷基化剂的反应中,可以调整连续反应以提供优先的 O-或 C-烷基化,使用超临界丙烯进行高达 49% 的 O-烷基化。我们还研究了一系列环醚的合成,并展示了一种在非常温和的条件下从 1,4-丁二醇合成 THF 的改进方法。

  • Hydroxynitrile lyase catalyzed enantioselective HCN addition to O-protected α-hydroxyaldehydes
    作者:Jürgen Roos、Franz Effenberger
    DOI:10.1016/s0957-4166(99)00275-x
    日期:1999.7
    Various O-protected glycol- and racemic lactaldehydes 3 and 6 as well as O-allyl protected racemic alpha-hydroxyaldehydes 7 (R-1=Et Pr, Bu) have been prepared to investigate and perform a stereoselective Kiliani-Fischer synthesis by hydroxynitrile lyase (HNL) catalyzed addition of HCN. From all protecting groups investigated the allyl moiety was most suitable. (R)-PaHNL from bitter almonds (Prunus amygdalus), yielding the (2S)-cyanohydrins 8-10, was found to be a more stereoselective catalyst than (S)-MeHNL from maniok (Manihot esculenta). While (R)-PaHNL led to enantiomeric excesses greater than or equal to 93%, with (S)-MeHNL the (2R)-cyanohydrins 8-10 were obtained with enantiomeric excesses less than or equal to 78%.
