  Stereoselective intramolecular coupling of diaroylacetates of (1R,1′R)-exo,exo′-3,3′-biisoborneol by oxidation with Br2

  摘要：

  The oxidative coupling of diaroylacetate derivatives prepared from (1R, 1'R)-exo,exo'-3,3'-biisoborneol with NaH-Br-2 gave the corresponding intramolecularly coupled products stereoselectively. The major (R,R)-isomers thus obtained were transformed to (-)-Sesamin and (-)-Eudesmin. (C) 2003 Elsevier Ltd. All rights reserved.
