  • Highly Stereoselective Iodolactonization of 4,5-Allenoic Acids-An Efficient Synthesis of 5-(1′-Iodo-1′(<i>Z</i>)-alkenyl)-4,5-dihydro-2(3<i>H</i>)-furanones
    作者:Xinpeng Jiang、Chunling Fu、Shengming Ma
    DOI:10.1002/chem.200801363
    日期:2008.10.29
    In this paper, it is reported that the efficient iodolactonization of 4,5-allenoic acid with I2 in cyclohexane in the presence or absence of K2CO3 afforded 5-(1'-iodo-1'(Z)-alkenyl)-4,5-dihydro-2(3H)-furanones highly stereoselectively. However, the reaction of axially optically active 4,5-allenoic acids (R)-(-)-5 a and (R)-(-)-5 b with I2 afforded the corresponding products with a serious loss of chirality
    在本文中,据报道,在存在或不存在K2CO3的条件下,在环己烷中用I2对4,5-烯丙酸进行有效的碘内酯化,可得到5-(1'-碘-1'(Z)-烯基)-4,5 -dihydro-2(3H)-呋喃酮具有高度立体选择性。然而,轴向旋光的4,5-烯丙酸(R)-(-)-5a和(R)-(-)-5b与I 2的反应提供了具有严重手性损失的相应产物。通过在Cs2CO3存在下用N-碘琥珀酰亚胺在CH2Cl2中进行碘内酯化解决了这个问题。然而,Z / E的选择性较低。通过随后的Sonogashira偶联动力学拆分,可以制备纯的光学活性Z产物。底物与起始4,5-烯丙酸的3位上的取代基反应得到反式4,5-二取代的γ-丁内酯是唯一的产品。4,5-烯丙酸(S)-(+)-1 l,(R)-(-)-1 l和(S)-(+)-1 m的反应在3处具有中心手性不管丙二烯部分的轴向手性如何,-位置提供的反式产物具有非常高的对映体纯度和高达98:2的Z
  • Studies on Pd<sup>0</sup>-Catalyzed Cyclization of<i>N</i>-3,4-Alkadienyl Toluenesulfonamides with Organic Halides: Selective Synthesis of 2,3-Dihydropyrroles, 1,2,3,6-Tetrahydropyrridines, and Azetidines

    日期:2007.1
    The palladium-catalyzed coupling-cyclization of beta-amino allenes with organic halides ranging from aryl halide to 1-alkenyl halide was studied. 2,3-Dihydro-1H-pyrroles were obtained by reaction of 3-substituted-5-unsubstituted-3,4-allenyl amides under conditions A, while the reaction of 5-substituted-3,4-allenyl amides afforded 1,2,5,6-tetrahydropyridines and/or azetidines with high de under conditions

  • Highly Regio- and Stereoselective Synthesis of 2(<i>E</i>),4-Alkadienoates via the Pd(0)-Catalyzed Reaction of Aryl Halides with 3,4-Alkadienoates
    作者:Chunling Fu、Shengming Ma
    DOI:10.1021/ol0473389
    日期:2005.4.1
    2(E),4-Alkadienoates were prepared highly stereoselectively via the Pd(O)/Ag2CO3-cocatalyzed reaction of 3,4-alkadienoates and aryl halides. The reaction is believed to proceed via the oxidative addition-carbopalladation-,beta-H elimination process. Compared to the other reported methods for the synthesis of 2,4-alkadienoates, in which usually only disubstituted C=C bonds were formed, the current reaction forms the trisubstituted or even tetrasubstituted C=C bond highly stereoselectively.
  • Efficient Synthesis of 4-(2‘-Alkenyl)-2,5-dihydrofurans and 5,6-Dihydro-2<i>H</i>-pyrans via the Pd-Catalyzed Cyclizative Coupling Reaction of 2,3- or 3,4-Allenols with Allylic Halides
    作者:Shengming Ma、Wenzhong Gao
    DOI:10.1021/jo0163997
    日期:2002.8.1
    In the absence of a base, palladium(II) catalysts, such as PdCl2, PdCl2(CH3CN)(2), Pd(OAc)(2), and [(pi-C3H5)PdCl](2), can catalyze the cyclizative coupling reaction of 2,3- or 3,4-allenols with allylic halides in DMA at room temperature to provide 2,5-dihydrofurans and 5,6-dihydro-2H-pyrans, respectively, in moderate to good yields. Under similar reaction conditions, nonsubstituted 2,3-allenol 1s affords bimolecular cyclizative coupling product 5s as the major product. The scope of the reaction and its mechanism have been studied briefly. On the basis of the experimental results, the transformation was believed to proceed via a divalent palladium-catalyzed pathway.
  • A palladium catalyzed efficient synthesis of γ-methylene-α,β-unsaturated γ-lactones via cyclization of 3,4-alkadienoic acids
    作者:Shengming Ma、Fei Yu
    DOI:10.1016/j.tet.2005.06.063
    日期:2005.10
    An efficient method was developed for the synthesis of gamma-methylene-alpha, beta-unsaturated gamma-lactones from the Pd-catalyzed cyclization of 3,4-alkadienoic acids. Control experiment shows that the reaction should be carried out under a N-2 atmosphere to ensure the high purity of the products. (c) 2005 Elsevier Ltd. All rights reserved.
