Abstract: The tandem asymmetric Michael addition/intramolecular nucleophilic substitution of the novel chiral source, 3-bromo-5-(1-menthyloxy)-2 (5H)-furanone (1) with some carbon nucleophiles has been investigated.The asymmetric reaction can yield optically pure 3-bicy-clo [3.3.0]octene derivatives containing two novel stereogenic chiral centers.The chemical structure and configuration of these 3-bicyclo[3.3.0]octene compounds were identified on the basis of their elemental analytical data and spectroscopic data, such as[α]D20, UV, IR,1HNMR, 13CNMR, MS and X-ray crystallography.This asymmetric reaction can provide an important strategy in synthesis of some optically pure 3-bicyclo[3.3.0]octene compounds and some biologically active molecules.
