A new series of 1-arylnaphthalene lignan analogs having a variety of pyridyl substituents at the C-1 position were synthesized in moderate to good yields by means of the Diels-Alder reaction by utilizing 1-pyridylisobenzofuran precursors with dimethyl fumarate, methyl acrylate, or dimethyl acetylene dicarboxylate, followed by BF3·Et2O-mediated aromatization.
利用Diels-Alder反应,利用1-吡啶基异苯并呋喃前体与富马酸二甲酯,丙烯酸甲酯或乙炔二甲酸二甲酯,然后由BF 3 ·Et 2 O介导的芳构化。
