mild, copper-catalyzed coupling of organoindium reagents with nitrogen-containing aromatic heterocycles and chloroformates is described. This reaction proceeds with a range of organoindium reagents, yielding predominately or exclusively the 1,4-addition products with pyridine. In addition, a range of other nitrogen-containing heterocycles can be employed in this reaction (e.g. benzoxazole, benzothiazole
描述了有机铟试剂与含氮芳香杂环和氯甲酸酯的温和铜催化偶联。该反应使用一系列有机铟试剂进行,主要或仅产生与吡啶的 1,4-加成产物。此外,在该反应中可以使用一系列其他含氮杂环(例如苯并恶唑、苯并噻唑、酞嗪)。作为该反应效用的说明,该杂环官能化与随后的氧化相结合以实现官能化吡啶和苯并噻唑衍生物的一锅法合成。
