6,6′-二羟甲基-2,2′-联吡啶(1)经与3,4-二氢吡喃(DHP)反应得到6-羟甲基-6′-四氢吡喃(THP)氧甲基-2,2′-联吡啶(2);化合物(2)经甲磺酰化和碘化反应得到6-碘甲基-6′-四氢吡喃氧甲基-2,2′-联吡啶(5);(2)和(5)经缩合、醇解反应得到双(6...6,6′-二羟甲基-2,2′-联吡啶(1)经与3,4-二氢吡喃(DHP)反应得到6-羟甲基-6′-四氢吡喃(THP)氧甲基-2,2′-联吡啶(2);化合物(2)经甲磺酰化和碘化反应得到6-碘甲基-6′-四氢吡喃氧甲基-2,2′-联吡啶(5);(2)和(5)经缩合、醇解反应得到双(6′-羟甲基-2,2′-联吡啶-6-甲基)醚(7);(7)与6,6′-二溴甲基-2,2′-联吡啶反应得到大环配体(8). 对中间体(2)的合成条件进行了探讨. 所有中间体和大环配体均经元素分析、1 H NMR、MS等证实了它们的结构和组成.展开更多
The 6-hydroxymethyl-6'-tetrahydropyranyloxymethyl-2, 2'-bipyridine (2) was synthesized by the reaction of 6,6'-dihydroxymethyl-2, 2'-bipyridine (1) with 3, 4-dihydroxypyran (DHP). 6.Tetrahydropyranylox...The 6-hydroxymethyl-6'-tetrahydropyranyloxymethyl-2, 2'-bipyridine (2) was synthesized by the reaction of 6,6'-dihydroxymethyl-2, 2'-bipyridine (1) with 3, 4-dihydroxypyran (DHP). 6.Tetrahydropyranyloxymethyl-6'-iodomethyl-2, 2'-bipyridine (5) was obtained from mesylate and iodizating reaction of compound 2. The coupling of 2 and 5 followed by hydrolysis gave bis(6'-hydroxymethyl-2, 2'-bipyridine-6-methyl) ether (7). The macrocyclic ligand 8 was obtained by treating 7 and 6, 6'-dibromethyl-2, 2'-bipyridine. The synthetic conditions of the intermediate 2 and macocyclic ligand 8 were discussed.展开更多
