  • Versatile Route to Benzoannulated Medium-Ring Carbocycles via Aryne Insertion into Cyclic 1,3-Diketones: Application to a Synthesis of Radermachol
    作者:Ramesh Samineni、Pabbaraja Srihari、Goverdhan Mehta
    DOI:10.1021/acs.orglett.6b01078
    日期:2016.6.17
    involving the insertion of in situ generated aryne into the C–C bond of cyclic 1,3-diketones for rapidly assembling functionalized benzo-fused medium ring carbocycles is delineated. The efficacy of the methodology has been demonstrated through a concise total synthesis of pentacyclic natural product radermachol.

    The red pigment, radermachol (1), has been synthesized from 1,4-dimethoxynaphthelene in thirteen steps.
  • Crystal and molecular structure of 6,7-benzo-3,4 (1,4-dimethoxy-2,3-naphtho)-1,5-dioxosuberane

    DOI:10.1007/bf01665273
    日期:1995.7
    The crystal and molecular structure of the title compound (2) C21H16O4 has been determined by an X-ray analysis, by direct methods from diffractometer data and refined by full-matrix least squares. The compound (2) crystallizes in the space group P2(1)/a, with cell parameters: 36.432(5), b = 5.512(3), c = 8.269(5) Angstrom, beta = 108.0(3)degrees, z = 4, D-c = 1.397 g/cm(-3), R = 7.8 for 1136 observed reflections. The conformation of the tetracyclic ring system shows a folding of two planar parts of the carbon skeleton about an axis passing thorough C8 and C16 of the seven membered ring C.

    Five different approaches to the preparation of 6,7-benzo-3,4-(1,4-dimethoxy-2,3-naphtho)-1,5-dioxosuberane (3), an intermediate needed for the synthesis of radermachol (1), the red pigment from the roots of Radermachera xylocarpa, are described. The synthesis of radermachol (1) has been accomplished from 1,4-nephthoquinone in 14 steps.

    日期:2000.4.1
    [formula: see text] Condensation of 3-phenylsulfonyl-1,3-isobenzofuranone (3) with benzocyclohept-6,7-en-5-ones such as 4 and 15 provides a straightforward, general method for synthesis of functionalized benzo[4,5]cyclohepta[1,2-b]naphthalenes (e.g., 5 and 16). This finding was used to achieve a brief and efficient preparation of 6,7-benzo-3,4-(1,4-dimethoxy-2,3-naphtho)-1,5-dioxosuberane (2), an established
