Thiazoles are important heterocyclic motifs in many target molecules. Extension of a reported gold(I)-catalyzed oxidative coupling of alkynes and thioamides to the synthesis of functionalized thiazole-containing products is presented, including the compatibility of this reaction with ester, protected hydroxyl, alkene and thioether groups. The utility of this one-pot process is demonstrated in the preparation
噻唑是许多靶分子中重要的杂环基序。提出了已报道的炔烃和硫代酰胺的金(I)催化的氧化偶联至官能化的含噻唑产物的合成,包括该反应与酯,被保护的羟基,烯烃和硫醚基团的相容性。一锅法的实用性在制备简化的帕他命A类似物的含噻唑的大环氧化物中得到了证明。
