摘要：

Limonene (1) was converted in one step into two diasteroisomers of 4,8-dimethyl-bicyclo[3.3.1]non-7-en-2-ol (2), useful as perfumes, employing PtCl2(PPh(3))(2)/PPh(3)/SnCl2 and PtCl2(diphosphine)/PPh(3)/SnCl2 systems as bifunctional catalysts whose diphosphines were 1,3-bis(diphenylphosphino)propane (dppp) and 1,4-bis(diphenylphosphino)butane (dppb). In the presence of the PtCl2(dppb)/PPh(3)/SnCl2 system, which was found to be the most promising combination,the selectivity for 2 reached the value of 82% at 95% conversion of 1.
