A highly stereocontrolled synthesis of furofuran lignans, (+/-)-Paulownin (1a) and (+/-)-Isogmelinol (1b) is described involving intramolecular radical cyclisation as a key step.

Four new lignans, (+)-1-acetoxypinoresinol-4'-β-D-glucoside (1), (+)-1-acetoxypinoresinol-4'-β-D-glucoside 4''-O-methyl ether (2), (+)-1-hydroxypinoresinol-1-β-D-glucoside (4) and (+)-fraxiresinol-1-β-D-glucoside (5), and a known lignan, (+)-1-hydroxypinoresinol-4'-β-D-glucoside (3), were isolated from the bark of Olea europaea L. and the bark of Olea africana MILL. (Olea europaea L. subsp. africana (MILL.) GREEN) (Oleaceae).Their structures were elucidated on the basis of spectroscopic analysis and chemical evidence.The bark of Olea capensis L. did not yield any lignan glucosides.Keywords - Olea europaea; Olea africana; Olea capensis; Oleaceae; lignan; (+)-1-acetoxypinoresinol-4'-β-D-glucoside; (+)-1-acetoxypinoresinol-4'-β-D-glucoside 4''-O-methyl ether; (+)-1-hydroxypinoresinol-4'-β-D-glucoside; (+)-1-hydroxypinoresinol-1-β-D-glucoside; (+)-fraxiresinol-1-β-D-glucoside
