  • Asymmetric synthesis of pentenomycin I, epipentenomycin I, and their analogs
    作者:Manat Pohmakotr、Supakeat Kambutong、Patoomratana Tuchinda、Chutima Kuhakarn

    日期:2008.6
    α-sulfinyl carbanions as an efficient and general synthetic approach for the preparation of (−)-pentenomycin I (1) and (−)-epipentenomycin I (5) and their enantiomers (ent-1 and ent-5), starting from chiral (2S,5S,6S)-ester 6 and ent-6, respectively, has been demonstrated. Easy accesses to pentenomycin analogs have also been demonstrated through the Pummerer, Suzuki–Miyaura, and Sonogashira reactions.
    α-亚磺酰基碳负离子分子内酰化反应的合成效用,是制备(-)-戊新霉素I(1)和(-)-表戊新霉素I(5)及其对映异构体(ent - 1和ent - 5),分别从手性(2 S,5 S,6 S)-酯6和ent - 6开始。通过Pummerer,Suzuki-Miyaura和Sonogashira反应也证明了易于获得戊喷霉素类似物。
  • An Improved Approach to Chiral Cyclopentenone Building Blocks. Total Synthesis of Pentenomycin I and Neplanocin A
    作者:John K. Gallos、Christos I. Stathakis、Stefanos S. Kotoulas、Alexandros E. Koumbis
    DOI:10.1021/jo050987t
    日期:2005.8.1
    An improved approach to enantiomerically pure hydroxylated cyclopentenones is reported here, which involves intramolecular nitrone cycloaddition of sugar-derived chiral pent-4-enals and hex-5-en-ones-2 followed by N−O bond cleavage, quaternization of the amine thus produced, and finally oxidative elimination of the amino group. Synthesis of pentenomycin I and neplanocin A is described following this
    本文报道了一种对映体纯的羟基化环戊烯酮的改进方法,该方法涉及糖衍生的手性五-4-烯醛和六-5-烯一酮-2的分子内硝酮环加成,然后进行N-O键裂解,使胺季化产生,最后氧化消除基。按照该方法描述戊糖霉素I和奈普兰霉素A的合成。
  • Asymmetric Intermolecular Pauson−Khand Reactions of Unstrained Olefins:  The (<i>o</i>-Dimethylamino)phenylsulfinyl Group as an Efficient Chiral Auxiliary
    作者:Marta Rodríguez Rivero、Juan Carlos de la Rosa、Juan Carlos Carretero
    DOI:10.1021/ja038491l
    日期:2003.12.1
    The first asymmetric version of intermolecular Pauson-Khand reactions of unstrained alkenes is described. Generally simple acyclic alkenes exhibit low reactivity and regioselectivity in intermolecular Pauson-Khand reactions; however, o-(dimethylamino)phenyl vinyl sulfoxide reacts under very mild conditions with a wide variety of terminal alkynes in a completely regioselective and highly stereoselective
    描述了无应变烯烃的分子间 Pauson-Khand 反应的第一个不对称版本。通常,简单的无环烯烃在分子间 Pauson-Khand 反应中表现出低反应性和区域选择性;然而,邻(二甲氨基苯基乙烯基亚砜在非常温和的条件下以完全区域选择性和高度立体选择性的方式与多种末端炔烃反应。抗生素 (-)-戊烯霉素 I 的非常短的对映选择性合成说明了所得 5-亚磺酰基-2-环戊烯酮在不对称合成中的应用。
  • Vinyl Sulfoxides as Stereochemical Controllers in Intermolecular Pauson-Khand Reactions: Applications to the Enantioselective Synthesis of Natural Cyclopentanoids

    diastereoselectivity (de=86->96 %, (S,R(S)) diastereomer). Experimental studies suggest that the high reactivity exhibited by the vinyl sulfoxide 1 i relies on the ability of the amine group to act as a soft ligand on the alkyne dicobalt complex prior to the generation of the cobaltacycle intermediate. On the other hand, both theoretical and experimental studies show that the high stereoselectivity of the process is
    描述了亚砜在不对称分子间Pauson-Khand反应中作为手性助剂的用途。在α,β-不饱和亚砜中筛选了原子上的各种取代基后,事实证明,现成的邻-(N,N-二甲基基)苯基乙烯基亚砜(1i)在氮气氛下可与取代的末端炔烃高度反应-氧化促进条件(CH3CN,0摄氏度)。另外,这些Pauson-Khand反应以完全的区域选择性和非常高的非对映选择性(de = 86-> 96%,(S,R(S))非对映异构体)发生。实验研究表明,乙烯基亚砜1 i表现出的高反应性取决于在生成环中间体之前,胺基团充当炔烃配合物上的软配体的能力。另一方面,理论和实验研究均表明,该方法的高立体选择性是由于所得的5-亚磺酰基-2-环戊烯酮加合物在C5中心容易发生热力学差向异构。当考虑到已知的不对称分子间Pauson-Khand反应仅限​​于使用高反应性的双环烯烃,主要是降冰片烯和降冰片二烯时,该新颖的方法构成了具有未应
  • A common and versatile synthetic route to (−) and (+) pentenomycin I, (+) halopentenomycin I and dehydropentenomycin
    作者:Sulagna Das、Amarendra Panda、Shantanu Pal
    DOI:10.1016/j.carres.2015.08.003
    日期:2015.10
    A versatile and stereoselective total synthesis of (+) and (-) pentenomycin I, (+) halopentenomycins I and dehydropentenomycin from a common chiral polyhydroxylated cyclopentene through oxidation and protection/deprotection has been described. Stereoselective hydroxymethylation, stereoselective Grignard reaction and ring closing metathesis are the key features of our approach.
