  A Novel Entry to Functionalized Benzofurans and Indoles via Palladium(0)-Catalyzed Arylative Dearomatization of Furans

  摘要：

  A novel entry to functionalized benzofurans and indoles from furans in moderate to good yields has been developed. This protocol involves palladium(0)-catalyzed dearomatizing intramolecular arylation of the furan ring, formation of a pi-allylic palladium complex, furan ring opening, and a beta-hydride elimination sequence.

  ion activation of the diene. A purely amine promoted formal inverse electron demand Diels–Alder cycloaddition approach was also demonstrated in the 2:1 coupling of 2,4-hexadienal with methanol. These reactions demonstrate the concepts of dual metal/amine catalysis and amine promoted formal inverse electron demand Diels–Alder cycloadditions. They differ from known examples of organocatalyzed Diels–Alder

  反应前瞻性研究导致发现Sc（OTf）3促进了咪唑酮或苯并呋喃取代的烯醛与吗啉的新型AA'B 2：1偶联。相关的Sc（OTf）3证明了吗啉促进的反应用于苯并呋喃取代的烯醛与二氢呋喃的偶联。这些加合物的形成与形式上的逆电子需求Diels-Alder环加成相一致，最有可能通过逐步发生的多米诺米歇尔-曼尼希（Domino Michael-Mannich）环化过程，涉及二烯的亚胺离子活化。在2，4-己二醛与甲醇的2：1偶联中也证明了纯胺促进了形式逆电子需求的Diels-Alder环加成反应。这些反应证明了双重金属/胺催化的概念，并且胺促进了形式逆电子需求Diels–Alder环加成反应。它们与已知的有机催化Diels-Alder反应的例子不同，在Diels-Alder反应中，二烯亲和物的亚胺离子活化或二烯的烯胺活化。
