  • Ni-Catalyzed Cycloisomerization between 3-Phenoxy Acrylic Acid Derivatives and Alkynes via Intramolecular Cleavage and Formation of the C–O Bond To Give 2,3-Disubstituted Benzofurans

    based on transition-metal-catalyzed C-O bond cleavage have attracted much attention as a new synthetic method. Until now, several intermolecular reactions via C-O bond cleavage of aryl ethers, alkenyl ethers, esters, and others have been reported. Here we report an unprecedented C-O bond cleavage of 3-phenoxy acrylic acid derivatives, followed by intramolecular C-O bond formation with alkynes. This reaction
    作为一种新的合成方法,基于过渡金属催化的CO键断裂的反应引起了人们的广泛关注。迄今为止,已经报道了通过芳族醚,烯基醚,酯等的CO键裂解的几种分子间反应。在这里,我们报告了前所未有的3-苯氧基丙烯酸衍生物的CO键断裂,随后与炔烃分子内形成CO键。该反应得到分别在2-和3-位具有有用的官能团-甲硅烷基取代基和丙烯酸衍生物的2,3-二取代的苯并呋喃。该报告还描述了对该机制的理论(DFT)见解。

    It has been established that a cationic rhodium(I)/BINAP complex catalyzes the cycloisomerization of 2-silylethynylphenols, leading to 3-silylbenzofurans, via 1,2-silicon migration. Similarly, the cycloisomerization of 2-silylethynylanilines, leading to 3-silylindoles, via 1,2-silicon migration was catalyzed by a cationic rhodium(I)/H8–BINAP complex.

  • GaCl<sub>3</sub>-Catalyzed Ortho-Ethynylation of Phenols
    作者:Katsumi Kobayashi、Mieko Arisawa、Masahiko Yamaguchi
    DOI:10.1021/ja026108r
    日期:2002.7.1
    Phenols are ethynylated at the ortho position with silylated chloroethyne in the presence of a catalytic amount of GaCl3 and lithium phenoxide. The lithium salt is essential for the catalysis, and addition of 2,6-di(tert-butyl)-4-methylpyridine inhibits desilylation and hydration of the products. The reaction can be applied to various substituted phenols giving the ortho-ethynylated products in high yields, and the turnover numbers based on GaCl3 are between 8 and 10. The reaction mechanism involves addition of in situ formed phenoxygallium to the haloethyne followed by the elimination of GaCl3.

    heterocyclic compounds. We achieved palladium-catalyzed migratory cycloisomerization of 3-o-alkynylphenoxy acrylic acid ester derivatives to give 2,3-disubstituted benzofurans. Although there are several reports of benzofuran synthesis with palladium-catalyzed migratory cycloisomerization, migratory groups are limited to allyl and propargyl groups. This report is the first example of benzofuran synthesis with
