The present invention is to prepare efficiently 2′-amino-5′-hydroxypropiophenone corresponding to the AB-ring part of camptothecin (CPT) skeleton and a tricyclic ketone corresponding to the CDE-ring part in order to provide efficiently CPT by the total synthesis, which is a starting material for irinotecan hydrochloride and various kinds of camptothecin derivatives, and to provide stably CPT and its derivatives.
本发明旨在高效制备与喜树碱(CPT)骨架 AB 环部分相对应的 2′-氨基-5′-羟基苯丙酮和与 CDE 环部分相对应的三环酮,从而通过全合成高效提供作为盐酸伊立替康和各种喜树碱衍生物起始原料的 CPT,并稳定提供 CPT 及其衍生物。
