A simple and efficient method for the combinatorial synthesis of highly substituted thiopyrano[3,4-b]pyridin-5(4H)-one, thiopyrano[3,4-b]quinoline-4,6(3H,5H)-dione, dithiopyrano[3,4-b:4′,3′-e]pyridine-4,6(1H,3H)-dione, and pyrazolo[3,4-b]thiopyrano[4,3-e]pyridin-5(1H)-one derivatives has been developed. The synthesis was achieved via one-pot multicomponent reaction of aromatic aldehyde, 2H-thiopyran-3
一种简单高效的方法,用于组合合成高度取代的噻喃并[3,4- b ]吡啶-5(4 H)-一,吡喃并[3,4- b ]喹啉-4,6(3 H,5 H) -二酮,二硫代吡喃并[3,4- b: 4',3'- e ]吡啶-4,6(1 H,3 H)-二酮和吡唑并[3,4- b ]硫代吡喃并[4,3- e已经开发了] pyridin-5(1 H)-one衍生物。通过芳族醛,2 H -thiopyran-3,5(4 H,6 H-二酮和烯胺(例如胺和1,3-二羰基化合物的衍生物和3-甲基-1-苯基-1 H-吡唑-5-胺)在冰醋酸中的含量。该方法的特点是反应时间短,通常收率高至优异,原料容易获得,操作简便。该化学为硫代吡喃并[3,4- b ]吡啶骨架的多样性导向构建提供了有效而有前途的合成策略。
