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.
