  A highly efficient regio- and enantioselective monohydrogenation of 1,4-dienes has been realized using an iridium catalyst with a chiral N,P-ligand under mild conditions. The substrate scope was studied and included both unfunctionalized as well as functionalized substituents on the meta- or para-position. Substrates having substituents with functionalities such as silyl protected alcohols or ketals

• Scalable Total Synthesis and Biological Evaluation of Haouamine A and Its Atropisomer
  作者：Noah Z. Burns、Irina N. Krylova、Rami N. Hannoush、Phil S. Baran

  DOI：10.1021/ja903745s

  日期：2009.7.8

  A total synthesis of the complex, bent aromatic ring-containing marine alkaloid haouamine A is achieved through a route in which every step (with the exception of the final deprotection) is performed on a gram-scale. This is accomplished through the development of a method for the dehydrogenation of cyclohexenones that allows for point-to-planar chirality transfer. This strategy makes it possible to program the desired atropisomeric outcome from a simple chiral cyclohexenone. By synthesizing atrop-haouamine A, this work has firmly established that natural haouamine exists as a single, nonequilibrating atropisomer. Finally, biological investigations demonstrate that the bent aromatic ring of this natural product is critical for anticancer activity against PC3 cells.
