Reaktionsschritte

(−) secoisolariciresinol (100 mg,) was dissolved in THF (5 ml) and to it was added a solution of triphenyl phosphine chloride in acetonitrile (1 ml) and the mixture was stirred at 0-80° C. for 1-10 hours. After completion of the reaction, the reaction mixture was concentrated under vacuum and the residue thus obtained was chromatographed over florosil column. Elution of the column with 30% EtOAC in pet. ether gave (−-3,4-divanillyl tetrahydrofuran (77 mg), m.p. 114-116° C.
