  • Synthesis of benzofuran derivatives through the coupling of conjugated dienynes with Fischer carbene complexes
    作者:James W Herndon、Yi Zhang、Haixia Wang、Ke Wang
    DOI:10.1016/s0040-4039(00)01574-4
    日期:2000.11
    The reaction of Fischer carbene complexes with conjugated dienylacetylene derivatives followed by treatment with iodine leads to benzofuran derivatives in good-to-excellent yields. Equivalent products can be obtained from coupling of conjugated enediynes with Fischer carbene complexes in the presence of hydrogen atom donors.
    Fischer卡宾配合物与共轭二烯基乙炔衍生物的反应,然后用碘进行处理,可以得到苯并呋喃衍生物,其收率非常好。在氢原子供体的存在下,将共轭二炔与菲舍尔卡宾配合物偶合可以得到等效的产物。
  • Coupling of Fischer carbene complexes with conjugated enediynes featuring radical traps: Novel structure and reactivity features of chromium complexed arene diradical species
    作者:Yi Zhang、Tareq Irshaidat、Haixia Wang、Kris V. Waynant、Haobin Wang、James W. Herndon

    The reaction of Fischer carbene complexes with conjugated enediynes that feature a pendant alkene group has been examined. The reaction proceeds through carbene-alkyne coupling to generate an enyne-ketene intermediate. This intermediate then undergoes Moore cyclization to generate a chromium complexed arene diradical, which then undergoes cyclization with the pendant alkene group. The radical cyclization prefers the 6-endo mode unless radical-stabilizing groups are present to favor the 5-exo mode. The intermediate diradical species were evaluated computationally in both the singlet and triplet configurations. Arene triplet diradicals feature minimal spin density at oxygen and delocalization to chromium. The 6-endo cyclization product was kinetically and thermodynamically favored. (C) 2008 Elsevier B.V.

    The cationic gold(I)-catalyzed reaction of 1-alkynyl-2-allylsilylbenzenes with water results in intramolecular allylation of the alkynes via 7-exo-dig cyclization to give 1,4-dienes in good yield with excellent stereoselectivities.
