以烯炔为反应原料, 在碱性条件下, 顺利地发生分子内串联反应合成了芳基萘类木脂素. 研究发现, 加入氟化银可以高效地促进反应进行. 实验结果表明, 以CH2ClCH2Cl作溶剂, 在AgF和K2CO3存在下, 烯炔可以顺利发生分子内串联反应, 高产率得到芳基萘类木脂素.

关键词: 氟化银, 烯炔, 串联反应, 芳基萘类木脂素

Base-mediated intramolecular cascade reactions of enynes were carried out smoothly leading to arylnaphthalene lignan lactones. The results demonstrated that aryl-substituted enynes successfully underwent the intramolecular cascade reaction to afford the corresponding arylnaphthalene lignan lactones in moderate to excellent yields using AgF/K2CO3 mixture as the bases in CH2ClCH2Cl. It is noteworthy that silver fluoride can promote the intramolecular cascade reaction.

Key words: silver fluoride, enyne, cascade reaction, arylnaphthalene lignan lactone
