実験手順: To a stirred mixture of 4-(1-(4-hydroxylphenyl)-2-phenylbut-1-enyl)phenol (500 mg, 1.0 eq), (S)-tert-butyl 2-(hydroxymethyl)pyrrolidine-1-carboxylate (480 mg, 1.5 eq) and PPh3 (625 mg, 1.5 eq) in 25 mL anhydrous THF under nitrogen was added DIAD (480 mg, 1.5 eq) dropwise at 0° C. The reaction was stirred for 48 h at rt. Then the reaction was quenched with water and extracted with EtOAc. The extract was dried, concentrated and purified by column chromatography to give the desired product (400 mg, 51% yield, Z/E=1/1). Then the reaction was quenched with water extracted with EtOAc The extract was dried concentrated purified by column chromatography
