The three-component reactions of 4-dimethylamino- or 4-methoxypyridine with acetylenedicarboxylates and arylidene cyanoacetates showed very interesting molecular diversity. The polysubstituted 1,8,9,9a-tetrahydro-4H-1,4-ethanoquinolizines, 2H-pyran-2,3-dicarboxylates, and buta-1,3-diene-1,2,4-tricarboxylates derivatives can be formed in high yields and with good diastereoselectivity depending on the
4-二甲基氨基或4-甲氧基吡啶与炔二羧酸酯和亚芳基氰乙酸酯的三组分反应显示出非常有趣的分子多样性。多取代的1,8,9,9a-四氢-4 H -1,4-乙基喹啉衍生物,2 H-吡喃-2,3-二羧酸盐和buta-1,3-二烯-1,2,4-三羧酸盐衍生物可以取决于底物和反应条件,可以高收率和良好的非对映选择性形成二价铁。
