    isotopic effect indicated that aromatic C-H bond cleavage is not involved in the rate-determining steps of the present transformation. Moreover, the results clearly demonstrate that the dichotomous catalytic behavior of the iron catalyst, which is transition-metal catalyst in the oxidative coupling step and Lewis acid in the condensation step. The possible intermediate 5 was synthesized and converted

  • Tandem Oxidation/Cyclization Reaction of 4-(Arylmethyl)oxy-2-diazobutyrate Derivatives

    日期:——
    A tandem oxidation/cyclization reaction of gamma-(arylmethyl)oxy-alpha-diazobutyrate derivatives was investigated. While oxidative cleavage of the PMB ether was only observed upon treatment of an alpha-diazo-beta-ketoester with DDQ, oxidation of alpha-diazo esters with an sp(3) carbon at the beta-position was accompanied by intramolecular attack of the diazo carbon atom and expulsion of the nitrogen gas to give 2,3-dihydrofurans in modest to good yields when an electron-withdrawing group was substituted at the beta-position. Substrates bearing no electron-withdrawing beta-substituent were found to give rearranged products, albeit in modest yields. A benzofuran derivative could also be obtained, although a hydroquinone adduct was formed as a byproduct.

    A concise and highly efficient synthetic pathway was developed for 2-substituted methyl benzo[b]furan-3-carboxylates. This method provides convenient and cost-effective access for 2-substituted methyl benzo[b]furan-3-carboxylates without the use of a transition metal catalyst for synthesis. Furthermore, in most cases, this method gives excellent yields and conventional flash column chromatography is not needed for purification.

    日期:2011.7.1
    benzofuran reduction (Mg, MeOH, NH4Cl) provides a convergent and modular synthetic route to trans-2-aryl-2,3-dihydrobenzo[b]furan-3-carboxylates, which are a structural feature of numerous biologically active natural products. This versatile strategy was applied to the formal total synthesis of the anti-HIV natural product (+)-lithospermic acid.
