A convenient and stereoselective synthetic route to the precursor of natural products, lignans, containing tetrahydrofuran has been developed. A series of asymmetric 2-aryltetrahydrofuran-3,4-carboxylic acid derivatives were synthesized in high yields with this route. The effect of substituents on the Diels-Alder reaction of aryl-substituted oxazoles with alkyne dienophile and on the catalytic hydrogenation
已经开发了一种方便且立体选择性的合成路线,以合成含有四氢呋喃的天然产物前体木脂素。采用该路线以高收率合成了一系列不对称的 2-芳基四氢呋喃-3,4-羧酸衍生物。已经研究了取代基对芳基取代的恶唑与炔烃亲二烯体的Diels-Alder反应以及对2-芳基呋喃-3,4-二羧酸二甲酯催化氢化的影响。还研究了二甲酯基团的区域选择性水解。所有产品均通过元素分析、FT-IR、1H NMR 和 MS 进行了表征。
