  The natural alkaloid isoanabasine: synthesis from 2,3′-bipyridine, efficient resolution with BINOL, and assignment of absolute configuration by Mosher’s method

  摘要：

  A highly efficient and practical resolution or racemic 1-benzyiisoanabasine, which was synthesized by reduction of the benzyl salt of 2,3'-bipyridine, has been achieved through molecular complexation with (R)-BINOL or (S)-BINOL to afford pure enantiomers (100% ee). The two enantiomers of the natural alkaloid isoanabasine have been obtained by debenzylation of the corresponding enantiomeric 1-benzylisoanabasine. Using Mosher's method by NMR techniques, the absolute configuration of (-)-isoanabasine has been assigned as the (R)-configuration for the first time. Moreover, an unexpected rotamer ratio of Mosher's amide was observed. The sYn-form of two rotamers of (R)-MTPA-(R)-isoanabasine was predominant over the anti-form. (c) 2005 Elsevier Ltd.
