  • High‐Yielding Synthesis of the Anti‐Influenza Neuraminidase Inhibitor (−)‐Oseltamivir by Two “One‐Pot” Sequences
    作者:Hayato Ishikawa、Takaki Suzuki、Hideo Orita、Tadafumi Uchimaru、Yujiro Hayashi
    DOI:10.1002/chem.201001108
    日期:2010.11.8
    Michael reactions, a thiol Michael reaction, and a base‐catalyzed isomerization. Six reactions can be successfully conducted in the second one‐pot reaction sequence; these are deprotection of a tert‐butyl ester and its conversion into an acyl chloride then an acyl azide, Curtius rearrangement, amide formation, reduction of a nitro group into an amine, and a retro Michael reaction of a thiol moiety. A column‐free
    通过使用两个“一锅”反应序列可实现有效的不对称总合成(-)-oseltamivir(一种抗病毒剂),其总收率极佳(60%),并且仅需通过柱色谱法纯化一次即可。第一个单锅反应序列由二苯基脯氨醇甲硅烷基醚介导的不对称迈克尔反应,多米诺骨牌迈克尔反应/霍纳-沃兹沃思-埃蒙斯反应与逆醛醇/霍纳-沃兹沃斯-埃蒙斯反应和逆迈克尔反应,硫代迈克尔反应组成,以及碱催化的异构化。在第二个“一锅法”反应序列中可以成功进行六个反应。这些都是去保护叔-丁基酯及其转化为酰氯,然后转化为酰叠氮,Curtius重排,酰胺形成,硝基还原为胺以及硫醇基团的逆迈克尔反应。还建立了(-)-奥司他韦的无柱合成方法。
  • High-Yielding Synthesis of the Anti-Influenza Neuramidase Inhibitor (−)-Oseltamivir by Three “One-Pot” Operations
    作者:Hayato Ishikawa、Takaki Suzuki、Yujiro Hayashi
    DOI:10.1002/anie.200804883
    日期:2009.2.2
    Taking shortcuts: A remarkably short and high‐yielding asymmetric total synthesis of ()‐oseltamivir takes advantage of organocatalysis and single‐pot domino operations. The target, known as the drug Tamiflu, is prepared efficiently in a short time, and also its derivatives can be synthesized effectively.
    走捷径:(-)-奥司他韦的明显短且高产的不对称总合成利用了有机催化和单罐多米诺骨牌操作的优势。可以在短时间内有效地制备称为药物达菲的靶标,并且还可以有效地合成其衍生物。
  • One-Pot Synthesis of (−)-Oseltamivir and Mechanistic Insights into the Organocatalyzed Michael Reaction
    作者:Takasuke Mukaiyama、Hayato Ishikawa、Hiroyuki Koshino、Yujiro Hayashi
    DOI:10.1002/chem.201302371
    日期:2013.12.23
    The one‐pot sequential synthesis of (−)‐oseltamivir has been achieved without evaporation or solvent exchange in 36 % yield over seven reactions. The key step was the asymmetric Michael reaction of pentan‐3‐yloxyacetaldehyde with (Z)‐N‐2‐nitroethenylacetamide, catalyzed by a diphenylprolinol silyl ether. The use of a bulky O‐silylsubstituted diphenylprolinol catalyst, chlorobenzene as a solvent, and
    (-)-奥司他韦的一锅法连续合成无需蒸发或溶剂交换即可完成,在七个反应中的收率为36%。关键步骤是在二苯基脯氨醇甲硅烷基醚的催化下,戊烷-3-基氧基乙醛与(Z)-N -2-硝基乙烯基乙酰胺的不对称迈克尔反应。使用大体积的O-甲硅烷基取代的二苯基脯氨醇催化剂,氯苯作为溶剂和HCO 2 H作为酸添加剂,对于生产首个具有出色收率以及出色的非对映和对映选择性的迈克尔加成物至关重要。对酸作用的研究表明,酸添加剂不仅可以加速E - Z戊烷-3-基氧基乙醛衍生的烯胺与二苯基脯氨醇甲硅烷基醚异构化,但环丁烷中间体的开环以及烯胺与(Z)-N -2-硝基乙烯基乙酰胺的加成反应。考虑到迈克尔产物的主要和次要异构体的绝对构型以及迈克尔反应的结果,提出了戊烷-3-基氧基乙醛与(Z)-N -2-硝基乙烯基乙酰胺的迈克尔反应的过渡态模型戊-3-基氧基乙醛与苯基马来酰亚胺和萘醌的混合物
