  • Total Syntheses of (−)-Herbertenediol, (−)-Mastigophorene A, and (−)-Mastigophorene B. Combined Utility of Chiral Bicyclic Lactams and Chiral Aryl Oxazolines
    作者:Andrew P. Degnan、A. I. Meyers
    DOI:10.1021/ja984182x
    日期:1999.3.1
    A nonracemic bicyclic lactam has been used to construct a chiral cyclopentane containing vicinal quaternary carbon centers in optically pure form, which is common to all of the title compounds. An oxazoline-mediated asymmetric Ullmann coupling was then utilized to establish chirality about the biaryl axis of mastigophorenes A and B. Through the course of this synthesis, it was clearly demonstrated

    The stereoselective total synthesis of the sesquiterpene herbertenediol (3) and of its naturally occurring dimers, mastigophorenes A [(P)-1] and B [(M)-1], is described. Following the “lactone concept”, the configuration at the biaryl axis was atropo-divergently induced to be P or, optionally, M, by stereocontrolled reductive ring cleavage (diastereomeric ratio up to 97:3) of the configurationally

    作者:Gerhard Bringmann、Stefan Tasler

    日期:2001.1
    products and related compounds in the fields of biphenyls, biscarbazoles and bisnaphthylisoquinolines. For sterically more hindered biaryls, which consequently show the phenomenon of axial chirality, the products were prepared in an atropisomerically pure form. Their absolute axial configurations were assigned mainly by experimental and computational CD investigations.

    The atroposelective ring cleavage of configurationally unstable biaryl lactones, by dynamic kinetic resolution, is an efficient tool for the stereoselective synthesis of axially chiral biaryl target molecules. The recent extension of this methodology to the kinetic resolution of configurationally stable biaryl lactones and its application to natural product synthesis is described herein, exemplarily for the preparation of the nerve-growth stimulating dimeric sesquiterpene mastigophorene B.
