  • Total Asymmetric Synthesis of the Aphidicolin Derivative (11<i>R</i>)-(−)-8-Epi-11-hydroxyaphidicolin Using Tandem Transannular Diels−Alder/Aldol Reactions
    作者:Guillaume Bélanger、Pierre Deslongchamps
    DOI:10.1021/ol990341l
    日期:2000.2.1
    [reaction: see text] Aphidicolin unnatural derivative (2) was synthesized using a new tandem transannular Diels-Alder/aldol methodology. The 8-epi-aphidicolane skeleton is constructed in a highly diastereoselective manner and converted into (11R)-(-)-8-epi-11-hydroxyaphidicolin (2). An efficient method for the difficult C16 funtionalization is presented.

  • Transannular Diels-Alder/Intramolecular Aldol Tandem Reaction as a Stereocontrolled Route to (+)-Aphidicolin and its Isosteric C8-Epimer1
    作者:Dennis G. Hall、Pierre Deslongchamps
    DOI:10.1021/jo00129a021
    日期:1995.12
    The trans,syn,cis A.B.C.[6.6.7] tricyclic subunit of aphidicolin could be derived from the transannular Diels-Alder (TADA) reaction of a trans,cis,cis (TCC) cyclopentadecatriene. On the other hand, a trans,trans,cis (TTC) isomeric cyclopentadecatriene could lead to the trans,syn,trans tricyclic skeleton of aphidicolin's C8-epimer. Interestingly, semiempirical calculations have shown the latter to be isosteric with aphidicolin in respect to the four hydroxyl groups. The required TCC and TTC 15-membered macrocyclic trienes 46 and 59 were synthesized using modern methods of acyclic stereoselection such as an organocopper-based difunctionalization reaction, Evans' asymmetric aldol methodology and Wittig-Horner-Wadsworth reactions. At the end, an efficient macrocyclization protocol served in achieving the synthesis of the desired optically active precursors 46 and 59. Whereas TCC substrate 46 failed to realize a TADA cycloaddition for steric and conformational reasons, TTC cyclopentadecatrienal 59 led to a stereospecific TADA/aldol tandem reaction. In the first reported example of such a transformation, macrocycle 59 was thermolyzed (toluene, sealed tube, 210 degrees C, 18 h) in a single operation into tetracyclic product 61 containing six new stereogenic centers. Mechanistic considerations of this impressive conversion along with transition-state modeling are also presented. Further transformations of compound 61 culminating in stereospecific functionalization at C16 were performed by making use of an hydroxyl-directed epoxidation reaction leading to the advanced intermediate 67. Thus, this exploratory work demonstrates the value of a TADA/aldol route for the synthesis of the titled compounds and analogs thereof.
  • New Approach to Aphidicolin and Total Asymmetric Synthesis of Unnatural (11<i>R</i>)-(−)-8-Epi-11-hydroxyaphidicolin by Tandem Transannular Diels−Alder/Aldol Reactions
    作者:Guillaume Bélanger、Pierre Deslongchamps
    DOI:10.1021/jo0007635
    日期:2000.10.1
    The 8-epiaphidicolane skeleton (3) was formed in one key reaction by highly diastereoselective tandem transannular Diels-Alder (TADA)-aldol reactions from the trans-trans-cis trienic macrocycle (4). The unnatural derivative (11R)-(-)-8-epi-11-hydroxyaphidicolin (2) was thus constructed, and an original solution to the C16 functionalization problem of many aphidicolin (1) syntheses is presented.
    在一个关键的反应中,由反式-反式-三烯大环(4)的高度非对映选择性串联的环式Diels-Alder(TADA)-醛醇缩合反应形成了8-表二十二烷骨架(3)。因此,构建了非天然衍生物(11R)-(-)-8-epi-11-羟基aphidicolin(2),并提出了解决许多Aphidicolin(1)合成的C16功能化问题的原始方法。
