Novel seco-analogs of CC-1065 1 were synthesized from comercially available nitroaniline by reduction, bromination, bisulfonation and bisallylation followed by reaction with tert-butyllithium, zirconocene and iodine. The obtained quinoline 6 was then transformed into 17 and 18, which, upon treatment with Pd0, led to 21 and 22, respectively. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany
CC-1065 1 的新型 seco-analogs 是由市售的硝基苯胺通过还原、溴化、双磺化和双烯丙基化,然后与叔丁基锂、二茂锆和碘反应合成的。然后将获得的喹啉 6 转化为 17 和 18,在用 Pd0 处理后,分别产生 21 和 22。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
