  Synthesis of 18-Noranhydrocamptothecin Analogs Which Retain Topoisomerase I Inhibitory Function

  摘要：

  The total syntheses of compounds 2 and 3 are described. Key departures from previous routes to camptothecin from these laboratories involved (i) early incorporation of C-2 oxygen (see compound 9) and (ii) recourse to a Heck vinylation for installation of a hydroxymethyl equivalent on the pyridone (see transformation 15 --> 16). The final compounds are of considerable interest in that they are the most drastically modified E ring systems which retain topoisomerase I inhibitory function.
