摘要

Abstract An expedient four-step approach for the synthesis of a short library of original analogues of the Topo-I Luotonin-A inhibitor, substituted at their C 8-and N 15-positions, was investigated. This consists of Rutaecarpines formation, their Witkop–Winterfeldt oxidation followed ultimately with functional adjustment of the pyrroloquinolone intermediates. In the first step of these investigations, Rutaecarpines including the Topo-I ...
