  Distant Functionalization via Incorporation of Thiophene Moieties in Electrophilic Reactions Promoted by Samarium Diiodide

  摘要：

  [GRAPHICS]Methyl thiophene-2-carboxylate, methyl 3-(thien-2-yl)acrylate, and methyl 5,2'-bithiophene-2-carboxylate were utilized as the synthetic equivalents of pentanoate 5-anion, pentanoate 4,5-dianion, heptanoate 7-anion, and nonanoate-8,9-dianion. By the promotion of samarium diiodide, these thiophene incorporating compounds reacted with aldehydes, ketones, and conjugated esters regioselectively at the thienyl rings, Long-chain esters with remote hydroxyl and carboxyl groups, including an antiarthritis agent, a shellac component, and an inhibitory agent of spore germination, were prepared after reductive desulfurizatian on Raney nickel.

  The dicarbonylation of 1,3‐butadiene to adipic acid derivatives offers the potential for a more cost‐efficient and environmentally benign industrial process. However, the complex reaction network of regioisomeric carbonylation and isomerization pathways, make a selective and direct transformation particularly difficult. Here, we report surprising solvent effects on this palladium‐catalysed process

  将1,3-丁二烯二羰基化为己二酸衍生物可为更具成本效益和环境友好的工业生产提供潜力。然而，区域异构体羰基化和异构化途径的复杂反应网络使得选择性和直接转化特别困难。在这里，我们报道了在存在1,2-双-二叔丁基膦膦-二甲苯（d t bpx）配体的情况下，钯催化的这一过程产生了令人惊讶的溶剂影响，这些配体允许由1,3-丁二烯，碳形成己二酸酯二酯。一氧化碳和甲醇，在可扩展条件下具有97％的选择性和100％的原子经济性。在最佳条件下，可以以高至极好的收率获得各种1,2-和1,3-二烯的二酯和三酯。
