    Complexes of Borane and N-Heterocyclic Carbenes: A New Class of Radical Hydrogen Atom Donor
    摘要:
    Calculations suggest that complexes of borane with N-heterocyclic carbenes (NHC) have B-H bond dissocation energies more then 20 Kcal/mol less than free borane, diborane, borane-THF, and related complexes. Values are in the range of popular radical hydrogen atom donors like tin hydrides (70-80 Kcal/mol). The resulting prediction that NHC borane complexes could be used as radical hydrogen atom donors was verified by radical deoxygenations of xanthates by using either AIBN or triethylborane as initiator.

  • Modular Total Synthesis of Rhizopodin: A Highly Potent G-Actin Dimerizing Macrolide

    A highly convergent total synthesis of the potent polyketide macrolide rhizopodin has been achieved in 29 steps by employing a concise strategy that exploits the molecule′s C2 symmetry. Notable features of this convergent approach include a rapid assembly of the macrocycle through a site‐directed sequential cross‐coupling strategy and the bidirectional attachment of the side chains by means of Hor

  • Total Syntheses of the Histone Deacetylase Inhibitors Largazole and 2-<i>epi</i>-Largazole: Application of <i>N</i>-Heterocyclic Carbene Mediated Acylations in Complex Molecule Synthesis
    作者:Bo Wang、Po-Hsien Huang、Ching-Shih Chen、Craig J. Forsyth
    DOI:10.1021/jo102478x
    日期:2011.2.18
    Details of the evolution of strategies toward convergent assembly of the histone deacetylase inhibiting natural product largazole exploiting gamma,delta-unsaturated-alpha,beta-epoxy-aldehydes and a thiazole-thiazoline containing omega-amino-acid are described. The initial N-heterocyclic carbene mediated redox amidation exploying these two types of building blocks representing largazole's structural domains of distinct biosynthetic origin directly afforded the seco-acid of largazole. This was accomplished without any protecting groups resident upon either thioester bearing epoxy-aldehyde or the tetrapeptide. However, the ineffective production of largazole via the final macrolactonization led to an alternative intramolecular esterification/macrolactamization strategy employing the established two building blocks. This provided largazole along with its C2-epimer via an unexpected inversion of the alpha-stereocenter at the valine residue. The biological evaluation demonstrated that both largazole and 2-epi-largazole led to dose-dependent increases of acetylation of histone H3, indicating their potencies as class I histone deacetylase selective inhibitiors. Enhanced p21 expression was also induced by largazole and its C2 epimer. In addition, 2-epi-largazole displayed more potent activity than largazole in cell viability assays against PC-3 and LNCaP prostate cancer cell lines.
