  Efficient Construction of the Oxatricyclo[6.3.1.0^0,0]dodecane Core of Komaroviquinone Using a Cyclization/Cycloaddition Cascade of a Rhodium Carbenoid Intermediate

  摘要：

  The rhodium(ll)-catalyzed cyclization/cycloaddition cascade of a o-carbomethoxyaryl diazo dione is described as a potential route to the oxatricyclo[6.3.1.0(0,0)]dodecane substructure of the icetexane diterpene komaroviquinone. The initially formed carbonyl ylide dipole prefers to cyclize to an epoxide at 25 degrees C but can be induced to undergo cycloaddition across the tethered pi-bond at higher temperatures.

• A Rh(II)-catalyzed cycloaddition approach toward the synthesis of komaroviquinone
  作者：Albert Padwa、Majid J. Chughtai、Jutatip Boonsombat、Paitoon Rashatasakhon

  DOI：10.1016/j.tet.2008.01.129

  日期：2008.5

  Using a rhodium (II)-catalyzed cyclization/cycloaddition sequence as the key reaction step, the icetexane core of komaroviquinone was constructed by an intramolecular dipolar-cycloaddition of a carbonyl ylide dipole across a tethered pi-bond. The ylide was arrived at by cyclization of a rhodium carbenoid intermediate onto a proximal ester group. Efforts toward the preparation of the required precursor for elaboration to the natural product are discussed. (C) 2008 Elsevier Ltd. All rights reserved.
